NWS NCEP CPC USDA Products Agricultural Weather Assessments World Agricultural Outlook Board * Random sampling of available daily weather data Location of weather stations received daily via the WMO1 * Most have data since at least 1982 (many with normals) 1 Agricultural Weather Assessments World Agricultural Outlook Board United Nations World Meteorological Organization Data, Products, and Services (in support of WAOB/JAWF) Secondary sources of weather data WMO (~70) Rain Gauge (900+) Data obtained by CPC from the Mexican weather bureau are incorporated into the weekly rainfall chart created for the Weekly Weather and Crop Bulletin and are provided separately to USDA analysts for their analysis of crop weather impacts. Agricultural Weather Assessments World Agricultural Outlook Board Data, Products, and Services (in support of WAOB/JAWF) Secondary sources of weather data Weekly Rainfall (mm) April 11-17, 2010 (WMO) Weekly Rainfall (mm) April 11-17, 2010 (Mexican Rain Gauge) 0-1 mm 1-10 mm 10-25 mm 0-1 mm 1-10 mm 10-25 mm 25-50 mm 50-100 mm > 100 mm 25-50 mm 50-100 mm > 100 mm The maps above highlight the differences that arise using WMO data, which are sparse in coverage, versus the supplemental rain gauge data, which provides a denser network of stations and a better representation of rainfall.
