National Drought Impact Monitoring- A NOAA NDVI and precipitation data study of Ethiopia

Författare

Summary, in English

This is a study on the potential of NOAA satellite data for operational early warning and food security monitoring at a national level.

Ethiopian NOAA NDVI 15-day composites (1981-1985) are analysed and compared to precipitation data including time series records from more than 200 stations. Anomaly analyses are introduced and the regional distribution of the 1984 drought is clearly identified. A strong relationship betwen satellite vegetation index anomalies and precipitation anomalies is demonstrated.

It is concluded that NOAA NDVI GAC data can be used as an essential input to a national early warning and food security monitoring system if restricted to the drylands of Ethiopia.
