Crop Explorer User Guide

The Crop Explorer Web Site features near-real-time global crop condition information based on satellite imagery and weather data. Thematic maps of major crop growing regions depict vegetative vigor, precipitation, temperature, and soil moisture. Time-series charts depict growing season data for specific agro-meteorological zones. Regional crop calendars and crop area maps are also available for selected regions.

Thematic maps are viewed at the regional level and can be selected for any 10-day period in the current growing season. Previous growing seasons can be selected from the dropdown list for the last two complete years. Historical data is available upon request. Thematic maps are grouped into three categories: Weather; Soil Moisture; and Vegetation Index. Time-series charts depict the same set of data types but for sub-regions that define specific agro-meteorological zones. The subregions are organized by country and in some regions, ranked by commodity production.
