TL;DR
This paper presents a method using FIR radiometers to detect cloud cover in the field of view of atmospheric Cerenkov telescopes, enhancing the accuracy of atmospheric measurements.
Contribution
It introduces a new technique employing FIR radiometers to identify cloud presence, supported by models validated against measurements.
Findings
Models accurately represent radiative emission from clear and cloudy skies.
FIR radiometers effectively detect cloud cover in Cerenkov telescope observations.
The method improves atmospheric condition assessments for Cerenkov radiation studies.
Abstract
A technique for detecting the presence of cloud in the field of view of an atmospheric Cerenkov telescope using a far infra red radiometer is described. Models for the radiative emission from clear and cloudy skies are tested and found to represent the measurements.
