New VAP Yields Aerosol Optical Depth from Irradiance Measurements
The Shortwave Array Spectroradiometer-Hemispheric (SASHE) is a ground-based instrument that measures both direct and diffuse shortwave irradiance. SASHE provides hyperspectral measurements from about 350 nm to 1700 nm at a wavelength resolution from 1 to several nanometers. The SASHE Aerosol Optical Depth (SASHE AOD) VAP processes the files created by the SASHE Langley VAP to…

Rejected! Update to Langley VAP Dismisses Outliers
A Langley plot is a regression of log (signal) versus airmass. Under appropriate conditions, the Langley regression yields values that represent the response of an instrument in absence of atmosphere (i.e., at the top of atmosphere), and these values are ultimately useful for instrument calibration. The existing LANGLEY VAP (available through special request from the…

New Value-Added Product Provides Tropospheric Temperature Measurements
Temperature is one of the most fundamental atmospheric state variables and is crucial to the understanding of many meteorological processes. The Raman lidars at the ARM Climate Research Facility Southern Great Plains (SGP) and Tropical Western Pacific (TWP) Darwin sites are currently the only ARM active remote sensing instruments capable of profiling temperature through much…

Additional Data Added to Aerosol Optical Depth Product
Aerosol optical depth (AOD) measures total aerosol burden in the atmosphere. The spectral dependence of AOD, typically described by the Angstrom exponent, is also an indicator of particle size. Small Angstrom exponent values (near zero) indicate presence of large particles, and vice versa. The AOD value-added product (VAP) provides both the wavelength-dependent values of AOD…
