Chapter 3 __________________________________________________________ Selecting Location

VAISALA ________________________________________________________________________ 15

CHAPTER 3

SELECTING LOCATION

This chapter contains information on how to find a suitable location for

MW41 Sounding System.

Sounding Operation Room

Besides providing good working conditions for the operator, thesounding operation room protects the ground equipment. Below are listed

the environmental conditions for the indoor equipment. In addition, direct

weather influences must be totally excluded. Refer to the corresponding

documentation for specifications on the required conditions for

individual system components.

See the manufacturer's notes for additional information:

Environmental Requirements for Indoor Equipment:Temperature +10 ... +35 C

Humidity 0 ... 90 % RH, non-condensing

Environmental Requirements for Outdoor Equipment:

Temperature -40 +55CHumidity 0 100% RH

In a tropical environment, it is recommended that you install an air

conditioner in the sounding operation room.

Equip the sounding operation room with the following:

- Adequate lighting

- Grounded electrical power outlets located close to the instrument

tables

- Desk for handling the radiosonde before release

At all sounding sites where a stable line voltage is not secured, it is

recommended to install and constantly use an uninterruptible power

supply (UPS) to guarantee successful soundings. See sectionUsing

Uninterruptible Power System (UPS, Optional) with MW41 on page 20

for more information.


18/88


16 ___________________________________________________________________ M211429EN-E

Antennas

For best results, select an installation site for the antenna set that is:

- Clear of obstacles such as buildings, dense forests, or metal masts.

- Even, in other words, the ground is even and relatively firm.

A single tree has no significant effect on signal reception, unless it is

very dense or less than 20 meters from the antenna set. Sparse forest can

cause some attenuation but is usually not a real hindrance.

1203-133

Figure 3 Signal Path Line-of-Sight Requirement

Other antenna masts and metal structures of small diameter do not disturb

reception if situated more than 20 meters away from the antenna set.

Metal roofs or other large surfaces may reflect signals, causing short-

duration fading. Large obstacles may block reception. To maintain the

line of sight, ensure that the angle from the antenna to the top of large

obstacles is less than 10. SeeFigure 3 above.

Antenna Types

The sounding instrument requires antennas for GPS and UHF reception.

The following antennas manufactured by Vaisala can be used:

- GA31, GA31N and GA41 GPS antenna

- RB31 directional UHF antenna

- RM31N and RM32 omnidirectional UHF antenna

- CG31 portable antenna

NOTE Antenna description and installation instructions are provided with eachantenna.


19/88

Chapter 3 __________________________________________________________ Selecting Location

VAISALA ________________________________________________________________________ 17

Antenna Cables

The standard length of the antenna cable is 33 meters. Lay the cables in

protective tubing to avoid mechanical wear. Secure the maximumpossible clearance from radar antennas. See the appropriate antenna

User's Guide for details.

Balloon-Filling Shed

An appropriate balloon-filling shed enabling proper inflation and

handling of the balloons is essential for a successful radiosonde ascent.

Observe the following recommendations when operating hydrogen

balloons:

- Place the shed near the sounding operation room so that the

radiosonde operator is able to view the shed from a window or the

door of the sounding operation room.

- Avoid inflating the balloon in the same building where the sounding

operation room is located because of the risks related to handling

gases.

- Free the terrain around the shed of obstacles such as trees, telephone

poles, antenna structures, etc., that might prevent free ascent of the

radiosonde in windy conditions.

- Make sure the balloon-filling shed:- is large enough to allow the operator to handle all normal types of

balloons conveniently.

- has a doorway wide enough for you to carry an inflated balloon

through without the balloon touching sharp corners or anything else

that can break it.

- has its door on the leeward side of prevailing winds.

- has free space for the gas generator or gas cylinders if there is no

separate chamber for them outside the shed.

- has adequate ventilation, especially when the doors are closed.

- Make sure all electrical installations within the shed, both permanent

and temporary, are of spark-proof construction. Carry out regular

inspections to prevent any oversights.

- Ground the inflation nozzle (Vaisala Filling Balance) through a metal

plate fixed to the floor. Connect the nozzle permanently to a well-

grounded piping system or some other construction with good earth

contact.


20/88


18 ___________________________________________________________________ M211429EN-E

- Note that since hydrogen mixed with air is highly inflammable, the

use and storage of hydrogen generators or cylinders are subject to

safety regulations issued by authorities.

- Follow the Safety Instructions for Radiosonde Operators given in the

Radiosonde User's Guide when training personnel for radiosondeoperation at a new station.

For the operating system to function properly, make sure the following

settings have been selected and installed:

- The workstation has a network with TCP/IP Protocol installed.

- Time zone is GMT.

CAUTION When taking PCs not delivered by Vaisala into use, pay special attentionto energy saver and similar settings on your computer. On many

computers, the default settings can cause shutdown of computer parts if

there is a long time period with no input from the user, for example,

during a sounding. This might result in a lost sounding.

Using Uninterruptible Power System(UPS, Optional) with MW41

If the MW41 input power source, typically mains power, fails for some

reason, a UPS can be used to provide emergency power. The UPS

provides near-instantaneous protection from input power interruptions by

supplying energy to the connected devices.

To avoid any power interruptions, make sure that all sounding equipment

are connected through a UPS system. The sounding PC and the UPS are

connected with a USB cable. The correct USB connector is marked with

a UPS sticker at the back of the PC.

CAUTION Make sure to select the correct, country-specific output voltage on theUPS display. See the manufacturers instructions for more details.

The UPS includes internal batteries to provide power in case AC input

power is not available. Make sure to inspect the condition of the batteries

regularly and, if necessary, replace the batteries according to the

manufacturers instructions.

CAUTION Before taking the UPS into use, make sure the UPS internal batteries areconnected.

During a power interruption, the UPS provides power for 25 minutes,

after which Windows is run down. The rundown takes a maximum of 5

minutes. All other values are the default values provided by the UPS.

CHAPTER 5

INSTALLING SOFTWARE

This chapter provides information on how to install the required software

for Sounding System MW41.

NOTE If Vaisala has provided the computer for your Sounding System MW41,the software installation has been done by Vaisala. In this case, you may

skip this chapter and move on toChapter 6, Creating Connections, onpage 51.

Operating System Settings

For the operating system to function properly, make sure the following

settings have been selected and installed:

- The workstation has a network with TCP/IP Protocol installed.

- Time zone is GMT.

User Requirements for Installing theSoftware

To perform the needed installations, you need administrator rights for

Windows. Vaisala recommends that after the sounding software has been

installed, you access the sounding workstation PC with operator-level

privileges (not administrator).

NOTE When you install the MW41 sounding software, you must belong to theAdministratorslevel. See your operating system documentation for

more information.

NOTE On computers delivered from Vaisala, you need to give a password to logon to the PC as Administrator. The Administrator password is

adpw_VA1.

26 ___________________________________________________________________ M211429EN-E

Dividing Workstation's Hard Disk

Note that it is not absolutely necessary to divide the workstation's hard

disk into two partitions. However, by default, the sounding file and

message output folders are placed on the D: partition, if available.Having the archives separate from the system partition can make the files

easier to backup, for example, to a DVD-ROM.

On computers delivered by Vaisala the partitions are done as described

below, and this can be used as a recommendation for partitioning other

sounding workstations, if desired. Follow the Windows operating

system's instructions, and the instructions below.

- Make the C: partition 100 GB in size. This is the default installation

location for the MW41 sounding software. The path can also be

changed.

- Make the D: partition to contain the rest of the hard disk. Format this

partition to use the NTFS file system. This way you can use the

Windows backup feature to secure the content of the hard disk.

Installing Peripheral Devices

Serial Port Extension

It is likely that a serial port extension device is needed to meet the

requirements stated in sectionMW41 Sounding Workstation

Requirements on page 19.For computers not delivered by Vaisala, this is

your responsibility. Refer to the instructions supplied with the device.

Printer

If your MW41 sounding system includes a printer, set it up to work with

Windows. Refer to the instructions supplied with Windows and the

printer.

For instructions on adding a new printer, see DigiCORA SoundingSystem MW41 Technical Reference.

Creating Remote Connection

To connect remotely to an MW41 workstation, you must create a trusted

HTTPS connection. See the instructions in sectionCreating Trusted

HTTPS Connection below.

By default, the security certificate is a self-signed HTTPS certificate. For

instructions on changing the default certificate to that of a Certificate

Authority, see DigiCORA Sounding System MW41 Technical

Reference.

Creating Trusted HTTPS Connection

These instructions are for remote client use, that is, when you create a

remote connection to the sounding workstation from another PC.

Note that the procedure is slightly different for different browsers.

NOTE Remote access HTTPS connection to the MW41 computer requiresinbound port 8443 to be open in all firewalls active in the system.

Creating Trusted HTTPS Connection with GoogleChrome

If you use Google Chrome as your web browser, you must install the

security certificate using Internet Explorer, see sectionCreating Trusted

HTTPS Connection with Internet Explorer on page64 for instructions.

The security certificate cannot be installed with Chrome.

After you have installed the certificate with Internet Explorer and start

using Chrome, Chrome will also start using a safe HTTPS connection.

Note that in Chrome, https:is crossed out with a red line and a red cross

appears on the lock icon in the browser's address bar, seeFigure 24 on

page76 for an illustration. However, you do not have to worry about this:

Chrome still uses the security certificate in the same way as the other

browsers.

If are using a certificate signed by Certificate Authority and not the

default certificate, the markings will not appear in the address bar.
