| Zusammenfassung |
| This paper describes the All Sky Infrared Visible Analyzer (ASIVA), a
multi-purpose visible and infrared sky imaging and analysis instrument whose
primary function is to provide radiometrically calibrated imagery in the
mid-infrared (mid-IR) atmospheric window. This functionality enables the
determination of diurnal fractional sky cover and estimates of sky/cloud
temperature from which one can derive estimates of sky/cloud emissivity and
cloud height. This paper describes the calibration methods and performance
of the ASIVA instrument with particular emphasis on data products being
developed for the meteorological community. Data presented here were
collected during the Solmirus' ASIVA
campaign conducted at the Atmospheric Radiation Measurement (ARM) Southern
Great Plains (SGP) Climate Research Facility from 21 May to 27 July 2009.
The purpose of this campaign was to determine the efficacy of IR technology
in providing reliable nighttime sky cover data. Significant progress has
been made in the analysis of the campaign data over the past several years
and the ASIVA has proven to be an excellent instrument for determining sky
cover as well as the potential for determining sky/cloud temperature,
sky/cloud emissivity, precipitable water vapor (PWV), and ultimately cloud
height. |
