In Summary: Some key pointsIn Summary: Some key points
The project is a success only because of NMA’s open mindedness
Trained NMA staff did most of the work insures sustainability
Obtaining and processing raw satellite data was critical
Local calibration of satellite rainfall algorithm VERY important
Combining the different data sets helps to fill spatial and temporal gaps
Improving data access and use also VERY important.
The Map Rooms are built using IRI Data Library tools, which were then transferred to NMA: good example of technology transfer
NMA is less reluctant to shares the combined data

The three major components of the project
1. Organization and QC of station data: Challenging
2. Obtaining and processing raw satellite data: Daunting
3. Developing methodology and codes: Time consuming
