== About ==

This dataset is called "CPC/Famine Early Warning System Daily Estimates", also known as RFE2, Rainfall Estimates. The data are calculated by merging GTS gauge observations and 3 kinds of satellite estimates. (GPI, SSM/I and ASMU).

* Each file is a daily total, compressed with gzip. (A simple '''7z x''' using 7-zip from the command-line will unzip it).
* 2004/07/24 and 2007/11/13 are missing.
* Important: the data is ordered in rows starting at the South-most.
* And also, there range is supposed to be <300mm. I found some insane values - (1.2E7, 1.1E8, 2005/04/08 and 2005/08/13). Recommendation from NOAA was to apply the 300mm ceiling.

== Example Code ==
=== Java Daily Accumulation ===
Here's Java code to calculate daily precipitation, by summing the CPCs.
<nowiki>
DataInputStream dis = new DataInputStream(new BufferedInputStream(new FileInputStream(new File(infile))));
float[] data = new float[691200];

for (int record=1; record<=8; record++) {
for (int i=0; i<691200; i++) // Ignore -9999 (no data) - and 3.0* is for 3-hrly mm/hr
data[i]+=(3.0*Math.max(0,dis.readFloat()));
}
dis.close();
</nowiki>
