EWX Snippets: Display an Auto-updated Map of Our Data on Your Website

Introduction:

Snippets are easy-to-embed interactive maps of Geospatial Data. Snippets access the Climate Hazards Center Geospatial Data Store-most commonly used in the Early Warning eXplorer. The CHC maintains extensive data stores that can be easily accessed and regularly updated.


The Climate Hazards Center, as a part of FEWS NET, has vast information stored in the GeoEngine and Early Warning eXplorer. And yet, the most important decisions are local. The Snippets were developed to allow national, meteorological, hydrological, and agricultural agencies to easily set up localized web-mapping services. We hope that Snippets can help inform proactive decisions that enhance resilience.


Snippets are a free, publicly accessible way to display maps from our Early Warning Explorer (EWX) online application on your own webpage. To generate the code and markup needed to display your desired data, please visit our EWX Map Snippet Configurator tool.

Examples

Below are examples of Snippet maps highlighting Zimbabwe with the CHIRPS, CHIRPS-GEFs, and Early Estimate Forecast data sets.


Climate Hazards Center InfraRed Precipitation with Stations (CHIRPS):

A 30+ year quasi-global rainfall data set. Spanning 50oS-50oN (and all longitudes), starting in 1981 to near-presents, CHIRPS incorporates 0.05o-resolution satellite imagery with in situ station data to create gridded rainfal time-series for trend analysis and seasonal drought monitoring.





CHIRPS-GEFS 15 Day Forecast:

The CHIRPS-GEFS data set uses the higher spatial resolution of CHIRPS and the advanced forecasting ability of GEFS to provide weatehr forecasts, updated daily at a spatial resolution of 5 km. In blending CHIRPS and GEFS, GEFS is bias-corrected and downscaled with respect to CHIRPS.





Early Estimates Forecast Total Precipitation 12-pentad:

The CHC Early Estimates are regional rainfall maps designed to support agroclimatic monitoring. These maps, which are updated every five days with the latest CHIRPS data, show rainfall conditions for multiple accumulation periods. Forecasts provides an outlook using a 15-day forecast.
