Subject:
SGP/TWR/C1 - West-side 60m data incorrect due to low battery
DataStreams:sgp30twr60mC1.b1
Description:
A low battery voltage caused T, RH, and VP to be incorrect. Data may be missing from some 
of the second period because battery voltage dropped to zero at one point.
Measurements:sgp30twr60mC1.b1:
  • Temperature, air, 60-m height, 30-min intervals(temp)
  • Humidity, relative, on hybrid-b grid, derived from RUC model(rh)
  • Pressure, vapor, at 2-m height, 30-min intervals(vap_pres)
