Daily soil moisture readings used to determine the drought index are taken by which agency?

• A. DOF
• B. NWS
• C. USGS
• D. NOAA

Answer: (A)

Daily soil moisture readings play a key role in calculating the drought index because soil moisture directly reflects how dry the topsoil is and how available water is for plants and fuels. The agency responsible for collecting and maintaining these daily soil moisture measurements in this context is the Department of Forestry. They monitor moisture levels across forested and surrounding areas, and the data feed into the drought index used to gauge drought severity and inform fire danger assessments and related decisions. While the National Weather Service and NOAA provide weather and climate data that support drought monitoring, and the USGS collects hydrologic data as well, the routine daily soil moisture observations used for the drought index in this setting come from the forestry department’s monitoring program.
