Note that when using Air Temperature and RH to calculate the Heat
Index, the Air Temperature and RH must fall within these boundaries in
order for Heat Index to be calculated:
Air Temperature
≥ 80 °F
RH
≥ 40%
If either measurement is outside the boundary, the Heat Index will be
reported as N/A. The condition that caused the Heat Index not to be
calculated will also be specified. See Appendix F for more information on
Heat Index calculation.
Dew Point
Sensors: Sensors that measure Air Temperature and RH
Real Time Fields: (Air Temperature and RH) or Dew Point
See Appendix C for information on Dew Point calculation.
