RFE1.0 10-Day Rainfall Estimates
RFE 1.0 10-Day Africa rainfall estimates were produced from 1995-2000 by the Climate Prediction Center
in support of the USAID/FEWS project. Estimates were produced by combining satellite temperature data,
rain guage measurements, and modeled wind and relative humidity to obtain dekadal precipitation totals
from 20W-55E, 40S-20N with 0.1 degree resolution. For further explanation, see:
Objectively Determined 10 Day African Rainfall Estimates Created For Famine Early Warning Systems
RFE2.0 Rainfall Estimates -- operational
Beginning January 1, 2001 RFE version 2.0 replaced RFE1.0 as the operational CPC Africa rainfall algorithm.
Along with a dramatically reduced processing time, the new algorithm gives increased assuracy and enhanced
code portability. The output domain is 20W-55E, 40S-40N with a 0.1 degree resolution, and each day's time
scale is 6Z-6Z. Output files are in binary format containing a 751x801 array of floating point rainfall
estimates. Ten day estimates are created by summing daily output data. For additional information, see:
CPC Africa Rainfall Estimation 2.0 Technical Description.
Africa Hazards Assessments -- operational
Beginning in 2001, weekly meteorological Hazards Assessments are produced for the Africa continent to
monitor any weather or climate related areas of concern throughout the area. Beginning in February
2002, seperate graphic and text products were disseminated. All archived products from 2001 through
May 2002 are in .gif format, but the Hazard Explanations are simple .txt files beginning May 2002.
Africa Intertropical Convergence Zone Monitoring -- operational
Ten day mean positions of the Africa ITCZ have been monitored since 1988 for the region from 15oW to
35oE. Daily analyses of the ITCZ position are found by hand interpolation of 15o Celcius surface
dewpoint and modeled surface wind streamline maps. Dekadal values are simple averages of daily position,
and climatological means are computed using the previous years' analyses. Monitoring is done from April
thru October, and current products may be found at:
