A multispectral retrieval method is developed on the 100 km regional scale to extract
the temperature, particle size, fractional cover and 11-μm emissivity of clouds which
may be semitransparent in the infrared based on emitted radiances. The scheme utilizes
the nonlinear relationship between emitted radiances when clouds are semitransparent and...
One method of estimating the longwave radiative heating of the atmosphere is to
combine satellite observations of emitted radiances with those computed from synoptic
temperature and humidity profiles. Modeled and observed radiances are brought into
agreement by altering cloud properties or even by adjusting the temperature and water
vapor profiles....
Advanced Very-High Resolution Radiometer 4-km data were collected over the northeast Atlantic for May-August, 1995-1999. Aerosol optical depth was retrieved in cloud-free pixels. In pixels containing clouds from only single-layered, low-level systems, a retrieval scheme that accounts for partly-cloudy pixels was used to retrieve: cloud optical depth, droplet effective radius,...
A thermal infrared (TIR) camera is used to remotely sense the foliage temperature in a mountain valley. The foliage temperature is used as a proxy for air temperature and can be used to study and map the dynamics of the nocturnal, weak-wind boundary layer in this valley. All radiative flux...
The atmospheric sodium daytime abundance was measured for
Corvallis, Oregon, using direct absorption of sunlight by atmospheric
sodium atoms, as observed with an optical waveguide spectrum analyzer.
The disadvantage of the spectrum analyzer is that it can't resolve the
sodium D-lines (Its resolving power is 0.5 nm, which is approximately...
One kilometer Moderate Resolution Imaging Spectroradiometer (MODIS) observations for Terra (morning) and Aqua (afternoon) satellites were used to follow the morning to afternoon evolution of marine stratocumulus clouds that were affected by ship stack exhaust. The observations covered the summer months of 2002-2003 and August 2007 for marine layers off...
