RISMt. St. Helens' Aerosols: Some Tropospheric and Stratospheric Effects
Publisher: American Meteorological Society
Abstract: Aerosol optical depth measurements based on the attenuation of direct solar radiation before and after the six major explosive eruptions of Mt. St. Helens during 1980 are presented. These automated measurements are from a ...
Optical Extinction Spectroscopy at Moderate Resolution: Insights into Problems of Weak Absorption Bands
Publisher: American Meteorological Society
Abstract: Sunphotometry is a common technique for characterizing aerosol properties. Photometers used for these measurements have a series of narrow-band filters that are chosen to avoid molecular absorption features, except for the ...
Using a Blackbody to Calculate Net Longwave Responsivity of Shortwave Solar Pyranometers to Correct for Their Thermal Offset Error during Outdoor Calibration Using the Component Sum Method
Publisher: American Meteorological Society
Abstract: Thermopile pyranometers? thermal offset has been recognized since the pyranometer?s inception. This offset is often overlooked or ignored because its magnitude is small compared to the overall solar signal at higher ...
Optimal Measurement of Surface Shortwave Irradiance Using Current Instrumentation
Publisher: American Meteorological Society
Abstract: Although most measurements of total downwelling shortwave irradiance are made with pyranometers, the World Climate Research Program?s Baseline Surface Radiation Network has recommended the use of the summation of shortwave ...
The Arm Program's Water Vapor Intensive Observation Periods
Publisher: American Meteorological Society
Abstract: A series of water vapor intensive observation periods (WVIOPs) were conducted at the Atmospheric Radiation Measurement (ARM) site in Oklahoma between 1996 and 2000. The goals of these WVIOPs are to characterize the accuracy ...
