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.
