New Release of Reprocessed QCECOR Data
A new protocol for the QCECOR VAP at Lawrence Livermore National Laboratory has been developed. Quality-Controlled Eddy Correlation Flux Measurement (QCECOR) value-added product data were reprocessed for all the stations at the Southern Great Plains (SGP) site from year 2003 to the end of year 2015. The QCECOR data provide surface sensible and latent heat flux…

New Radiative Flux Analysis VAP Now Operational
Radiative flux analysis data of irradiance and cloud fraction are shown here for the Southern Great Plains. The Radiative Flux Analysis VAP is an implementation of a series of algorithms that estimate clear-sky broadband surface irradiances, cloud fraction, optical depth, cloud transmissivity, and cloud radiative effects. This VAP is an updated version of the Shortwave…

Py-ART 1.5.0 Now Available
This image shows how Py-ART’s new circular statistics functions can be used to extract texture information that is then used as a fuzzy logic gate classifier. These data are from the ARM C-SAPR at the Southern Great Plains site. The Python ARM Radar Toolkit (Py-ART) development team has released version 1.5.0. as an open-source Python…

Large-Scale Forcing Data for GoAmazon Now Available for Second IOP
Differences in radar and TRMM precipitation and their impacts on the vertical velocity are shown here. Taken during the dry season in September and October in 2014, constrained variational analysis of large-scale forcing data for the second intensive operational period (IOP) of the Green Ocean Amazon (GoAmazon2014/15) field campaign are now available. Combining U.S. and…

Surface Meteorological Data Overhaul Completed
As the ARM Facility grew in size and scope, meteorological datastreams also grew in complexity across all the ARM sites. In an effort to provide data product consistency, the task of reprocessing historical surface meteorology data was recently completed. As the ARM Climate Research Facility grew both in size and scope, it became important to…
