Agroclimatology Data

Agroclimatology Data

FEWS NET's Agroclimatology Team employs satellite remote sensing, atmospheric models, and land surface models to monitor and forecast growing conditions in countries where surface observations are often sparse. By using multiple sources of data, it is possible to develop a convergence of evidence regarding current and future agroclimatic conditions. Such evidence is a basic input to the analytical process for assessment of food insecurity in FEWS NET countries.

About Agroclimatology Data

FEWS NET's Agroclimatology Team uses remote sensing and output from atmospheric and land surface models to assess crop growing conditions across large areas. Remote sensing imagery is captured by instruments onboard satellites orbiting the Earth, while the models employ mathematical equations to simulate the physical processes occurring in the atmosphere and on the ground. Together they provide FEWS NET analysts with an overview of rainfall, temperature, vegetation, soil moisture, and surface water conditions.

The portals and tools listed below utilize remote sensing to provide useful insights relating to weather and climate.

Additional Tools Additional Tools
Early Warning eXplorer (EWX)

This interactive web-based mapping tool allows users to visualize continental-scale rainfall estimate (Climate Hazards Center InfraRed Precipitation with Station data, or CHIRPS), land surface temperature (LST), normalized difference vegetation index (NDVI) data and anomalies, and more at varied time steps and review time series analysis.

Use tool
Early Warning eXplorer Lite (EWX Lite)

This interactive web-based mapping tool allows users to visualize time series of rainfall, NDVI, evapotranspiration, land surface temperature, and snow water volume, where applicable. EWX Lite is better suited for areas with poor internet connectivity.

Use tool
Climate Engine

This portal allows users to analyze and interact with climate and land-surface environmental monitoring datasets in real-time to improve decision making related to drought, water sustainability, and agricultural productivity.

Use tool

This spatial analysis tool is designed for climatological analysis of historical rainfall and temperature data. These user-friendly tools can be used to create more accurate datasets, analyze seasonal trends and/or historical climate data, create visual representations of climate data, and create scripts (batch files).

Use tool
Geo Water Requirements Satisfaction Index (GeoWRSI)

This program runs a crop-specific water balance model for a selected region in the world, using raster data inputs to help assess and monitor crop conditions during the crop growing season, or can be regressed with yields to produce yield estimation models and yield estimates.

Use tool
Water Point Viewer – CHIRPS

The water point map viewer, which monitors 234 water points from Senegal to Somalia, will help a range of government and non-government actors understand the current availability of water for livestock and human consumption. This will inform food security analysis, humanitarian assistance planning, and a range of other activities.
