Wallops Flight Facility

KT-19 Pyrometer


Measurements Provided:
Remote measurement of surface temperature (i.e, sea surface or land surface temperature in clear conditions; cloud top temperature in cloudy conditions)

General Description:


Measurement Characteristics:
Overall estimate of uncertainty: 0.5K plus 0.7% of difference between scene temperature and sensor housing temperature

Other measurement characteristics (comments on signal/noise, bias limits, etc):
Sample Rate = 5 Hz, Spectral Range = 9.6-11.5 microns, Field of View = 2 degrees
