A Procedure for Estimating Cloud Amount and Height From Satellite Infrared Radiation Data
TLDR
In this paper, a simple objective technique is presented that integrates satellite-measured infrared radiation temperatures with the National Meteorological Center objective temperature analysis to yield cloud height and amount classification for small grid squares.Abstract:
A simple objective technique is presented that integrates satellite-measured infrared radiation temperatures with the National Meteorological Center objective temperature analysis to yield cloud height and amount classification for small grid squares. Sample of cloud information obtained by this technique from ITOS 1 data over the United States show good agreement with cloud observations obtained by surface observers and from aircraft reports. The method is completely automated and can be used to produce cloud analyses on a global scale.read more

The determination of sea-surface temperature from satellite high resolution infrared window radiation measurements
TL;DR: In this paper, a statistical histogram method is developed to objectively determine sea-surface temperature from satellite high resolution window radiation measurements, which involves inferring the distribution of surface radiances for the clear atmospheric case from observed histograms of generally cloud-contaminated radiances.

On the Infrared Transmission Through Cirrus Clouds and the Estimation of Relative Humidity from Satellites.
S. Fritz,P. Krishna Rao +1 more
TL;DR: In this paper, it was shown that at 10 μ the cirrus clouds had a fractional transmission of about 50%, while at 6 μ the clouds were essentially opaque, and the satellite data showed that measurements at 6 or 10 μ can be used to locate regions of substantial cloudiness, which are therefore regions of high relative humidity in the troposphere.
