Abstract

The remote sensing of water vapor from geostationary satellites, also known as 'reflectance technique,' was used to analyze three near-IR channels, one in the 0.94 micrometer vapor band absorption domain and the rest in neighboring atmospheric windows. Water vapor in the atmosphere reduces the intensity of solar radiation. Surface reflectance and the average atmospheric water vapor transmittance of the absorption were measured using the proposed near-IR reflectance technique.

Abstract

Three sets of precipitable water vapor observations over the Front Range of eastern Colorado in March 1990 are compared. The remote-sounding techniques used are emission, reflectance, and microwave. Horizontal and temporal resolutions of the various instruments account for the small variations between data sets. The reflectance and microwave readings agreed to within 0.1 cm. and those of the latter had similar correlations with the radiosonde readings. Variable terrain within the satellite footprint accounted for differences of 0.4 and 0.5 cm. between emission and microwave data.
