TABLES are available for the following reports:

• Data Completeness

• Quality Assurance

• Missing Stations

• Data Validity

• Watch List



Data Completeness

Percent of digital

data present for

-- TMAX

-- TMIN

-- TOBS

-- PRCP

-- SNOW

-- SNWD



Quality Assurance

Identifies the number

Of Errors, Time Shifts,

And Missing obs for

-- TMAX

-- TMIN

-- RN

-- SN



Missing Stations

List of active stations

That have not received

data for a period of time



Data Validity

Percent of unflagged and

non-missing data for

-- TMAX

-- TMIN

-- TOBS

-- PRCP

-- SNOW

-- SNWD

Does count missing

as not valid



Watch List

Identifies locations

with detected change-

points that do not

have corresponding

Metadata changes

These locations may

require additional

attention!

HoN Data Releases

Preliminary 1

Preliminary 2

Final Release



Preliminary 1 Release

-- Available 15-20 days after the end of the month

-- Based on NCDC’s TD3201 data.

-- TD3201 preliminary data are data received from sources such as ROSA, WXCODER, and IV-ROCS.

-- checks for and resolves basic internal inconsistencies by performing some very low-level quality control.



Preliminary 2 Release

-- Available approximately 60 days after the end of the month.

-- Based on NCDC’s TD3202 data.

-- TD3202 preliminary data undergo additional quality control steps over and above TD3201, in order to detect and remove precipitation outliers and key entry errors, and further resolve internal data inconsistencies.



Final Release

-- Available approximately 110 days after the end of the month

-- Based on NCDC’s TD3200 Published data

-- TD3200 data are the final data and have undergone full quality control processing at NCDC Resolutions to data

-- Discrepancies noted on this report should be reported via DATZILLA
