SUBJECT: Soil Moisture and Soil Temperature Data Entering
Hourly02 and Daily01 Products
Effective January 31, 2012
Effective Tuesday, January 31, 2012, at approximately 1500 Coordinated Universal Time (UTC), The National Climatic Data Center will begin populating the soil moisture and soil temperature fields for U.S. Climate Reference Network (USCRN) stations in the hourly02 (CRNH02) and daily01 (CRND01) products. The U.S. Historical Climatology Network-Modernization (USHCN-M) station soil fields in these product columns will continue to report missing values since only USCRN stations make soil observations.
For both products the fields for average soil moisture at 5cm, 10cm, 20cm, 50cm, and 100cm will each remain 7 characters in length, and will present fractional volumetric water content to the nearest thousandth. Soil moisture fields with missing data will have the number -99.000.
For both products, the fields for soil
temperature will remain
The documentation for both products will also be revised so that the soil moisture column names and definitions will clearly indicate that the fields contain fractional volumetric water content.
