     Final CHIRPS (all station data) is available sometime after the 15th of the following month. 

What is the temporal range for CHIRPS?

     CHIRPS is available from 1981 to near-real time
     The first couple of years are of lesser quality due to large gaps in the B1 IR data for that time period. 
     People using CHIRPS for hydrological modeling may choose to start later than 1981.
