Aerosol Size Distributions Obtained by Inversions of Spectral Optical Depth Measurements

Columnar aerosol size distributions have been inferred by numerically inverting particulate optical depth measurements as a function of wavelength. An inversion formula which ex...

Assessment of Atmospheric Limitations on the Determination of the Solar Spectral Constant from Ground-Based Spectroradiometer Measurements

Ground-based solar radiometer measurements have long been used to investigate various properties of both the Earth's atmosphere and the sun. This paper addresses the problem of ...

Design and Performance Analysis of an Automated 10-Channel Solar Radiometer Instrument

An automated multichannel solar radiometer has been designed and fabricated by the Atmospheric Remote Sensing Laboratory at The University of Arizona. The automated radiometer h...

A simple instrument and technique for measuring columnar water vapor via near-IR differential solar transmission measurements

A simple two-channel solar radiometer and data retrieval technique is described for sensing the columnar content of atmospheric water vapor via differential solar transmission m...
