Data Distribution System

Data Distribution System

• Select the data from the following choices– Data Categories, the sort of physical parameters( like SST,SSW and so

on)– Satellite or Sensors, etc

• Using shopping trolley icons, more user-friendly• Format exchange functions

　 AMSR/AMSR-E are HDF4,AMSR2 is HDF5, provided by these original format basically.– GeoTIFF,TIFF– netCDF(netCDF 4 classic model,CF-1.4)– HDF5(for AMSR-E/AMSR only)

Features of this system

Data Distribution System

• We will provide standard products through Data Distribution System( using online ,http,sftp) – Start to provide AMSR-E/AMSR2 soon (plan)– RA research and cooperate organizations

• Start to provide after initial checkout( 3month after the launch)– Other users

• Start to provide after the calibration/validation phase ( 1 year after the launch)

Provide plan

Level Contents

Level-1A• Swath data with geolocation information• Scene counts• ½ orbit starting from northern/southern-most latitudes

Level-1B• Swath data with geolocation information• Brightness temperatures• ½ orbit starting from northern/southern-most latitudes

Level-1R• Swath data with geolocation information• Spatial-resolution matched brightness temperatures• 4 resolution sets (6,10,23,36GHz) and raw swath for 89GHz A/B

Level-2• Swath data with geolocation information• Geophysical parameters (8 parameters)• ½ orbit starting from northern/southern-most latitudes

Leve-3• Grid data with 0.1/0.25 degrees (10/25km) resolution• Brightness temperatures and geophysical parameters• Daily and monthly temporal average• Equidistant Cylindrical and Polar Stereo Projection

• All products are in HDF5 format.

GCOM-W1 Processing Levels

Calibration/Validation• Validation by utilizing the existing observation networks:

– Radiosondes and GPS networks, SST and sea surface wind speed from various buoy system, Ground-based precipitation radar networks, Snow depth and other surface measurements by meteorological agencies, etc.

• Specific field campaigns/monitorings– Soil moisture test sites such as Mongolia, Thailand, and CEOP sites including Australia

Murray-Darling Basin, and Snow depth test site in Yakutsuk.• Potential interaction with other missions

– SMOS and SMAP for soil moisture, GPM GV collaboration for precipitation.

-New AWS testing in Metrological Institute since the beginning of June, untill September- After test, will install to Murry Darling Basin, north-west part of Melbourne, in Australia

Calibration/Validation (new tool)

Next PI meeting

・ PlanAround December or January in Tokyo, together with

other project ,GCOM-C, TRMM/GPM, EarthCARE, setting crosscutting discussion like the last year ,

(only plan, not discussed enoungh, not approved)

choices are - Just after 3rd RA selection, around September or October, 3rd RA

researhers only, introducing work plans each other.- Place ( Tokyo, or western part of Japan because of problems of

reactors and radiation.)

• The following problem are because of aging

- The antenna torque has been unstable than before - 89GHz-B Detector’s output voltage will reach upper limit soon

( expected, around this December)

• To make life longer - The operation to make the dynamic range of Tb a little narrow

=> details are reported EOC/MELCO
