OKMESO Soil Moisture Data (various OCS versions)
Please note that recent research focusing on the use of the Mesonet soil moisture sensors as soil temperature sensors demonstrated the following:
- The Mesonet soil moisture "start temperature" variable is not an accurate measure of soil temperature.
- Therefore, these data sets have no measure of soil temperature.
- Prior to January 2002, README files for Mesonet soil moisture data sets incorrectly stated:
"Because the soil moisture sensor operates by acquiring a temperature measurement before and after a heat pulse is applied, the 'pre-heating' temperature is a valid measurement of soil temperature co-located with the moisture measurement. These temperature measurements are accurate to 0.5 degrees C, and are included in this data."
- As a result, the Mesonet cannot at this time make a statement regarding the relationship between "start temperature" and soil temperature. The Mesonet research team regrets any inconvenience this has caused.
- With respect to volumetric water content, we are dealing with a derived value, the end product of a series of steps involving approximations and empirical coefficients that includes inherent error.
- Important note: For data downloaded through 1 April 2009, newer stations added after 2003 may not have had the WC values calculated. This has been corrected, and all stations should now have the WC values calculated using the same algorithm.
