• Real-time weather & early warning

• Agricultural assessments

• Household production of income & food

• Household consumption of income & food

• Coping strategies

• Water & sanitation conditions

• Healthcare• Health

Remotely sensed rainfall is essential for USAID applications in data poor regions

NOAA CPC RFE2 and ARC2 for near real-time monitoring in Africa.

TRMM and downscaled ERA-Interim recommended by collaborators for Middle East analysis

New, near real-time USGS CHIRP rainfall is available at 0.05 degree 1981-present (see poster)

First dekad (~10 day period) with >25 mm of total rainfall followed by a combined total of >20 mm in the following two dekads (AGRHYMET 1996).

Food Security is more than agricultural monitoring

Summary

IMERG/GPM may be an important additional source of information for near real-time monitoring.

The LIS team is implementing capabilities for GPM inputs, making them available for the FLDAS land surface models.

Longer term analysis, however, will have to be done with other rainfall products, until there is consistency with TRMM.
