------------
Title: TAMSAT (Tropical Applications of Meteorology using SATellite
       and ground-based observations)
Dates: Early 1980s to present

Title: TAMSAT Daily Rainfall Estimates (Version 3.0)
Description: The dataset comprises of high resolution (0.0375 degrees) 
             satellite-derived daily rainfall estimates for all Africa 
             from January 1983 to December 2016 (data from 2017 onwards
             can be downloaded from the TAMSAT website: 
             http://www.tamsat.org.uk). Further details can be found 
             in the daily data guide for users, available from the TAMSAT 
             website.

3. TERMS OF USE
-----------------
Please observe the TAMSAT data policy, available from: http://www.tamsat.org.uk/docs/TAMSAT_Data_Policy_2017.pdf 


4. CONTENT
------------
There is one zipped folder for each year, for example:

TAMSATv3.0_rfe_daily_YYYY.zip (where YYYY is the year)

Each zipped folder contains 12 sub folders for each calendar month. 
Each monthly folder contains all the available daily files. There is
one file for each day, for example:

rfeYYYY_MM_DD.v3.nc (where YYYY is the year, MM is the month and DD is the day)

The format of the data is netCDF.

There are also accompanying quicklooks (a png file) for each day. 


5. METHOD and PROCESSING
--------------------------
The TAMSAT daily estimates are derived from the pentadal (5-day) 
TAMSAT Version 3.0 rainfall dataset. Estimates are calculated by 
disaggregating the pentadal rainfall amounts to daily amounts 
according to the fraction of observed cold cloud duration (CCD) 
for each day. In this way, the 5-day sum of daily estimates equals 
the pentadal estimate, which is expected to be reliable.


6. ASSOCIATED DATASETS
------------------------
While the calibration used in TAMSAT Version 3.0 differs markedly from 
TAMSAT Version 2.0, the essence of the estimation approach remains the 
same as Version 2.0. Users are therefore advised to consult the following 
TAMSAT Version 2.0 publications which provides background to the TAMSAT 
estimation approach.
