Use of 0-200cm soil moisture to expand D0 in central NC

The North Carolina Drought Management Advisory Council (NCDMAC, which consists of multi-agency representatives from local through federal level) has a weekly videoconference to assess drought conditions across North Carolina and provide guidance/suggestions for the U.S. Drought Monitor (http://www.drought.gov/drought) product. Many factors are considered, including agricultural reports, stream levels, and rainfall distribution/deficit, to name but a few. The National Weather Service Office in Raleigh introduced and began to present SPoRT’s 0-200cm relative soil moisture products to the council in July. Soil moisture data, especially near-real-time data, is almost always difficult to find, and the NCDMAC typically relied on a rather sparse network of monitored wells and rainfall deficits as a proxy for quantitative analysis of a quality dataset. The data has been very well received and this week played a role in the council’s decision to recommend expansion of D0 across a major portion of the NC piedmont. The sub-county resolution was especially useful in determining where to ‘draw the line’, so to speak.

  1. Great post! I’m glad to see that you’ve found utility in using the LIS soil moisture data to make contributions to the U.S. Drought Monitor.
