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…

SACRCOR VAP Released to Evaluation
This is an example of gaseous attenuation corrected and masked for significant detection radar reflectivity (top) and dealiased radial Doppler velocity from the Ka-SACR. The ARM Facility is pleased to announce the release of Scanning ARM Cloud Radar (SACR) Corrected Moments (SACRCOR) to evaluation. SACRCOR, developed by the Clouds Research Group at McGill University and…

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…

Doppler Lidar Profile VAPs Now Available
Top: Height-time display of wind speed and direction.Bottom: Height-time displays of vertical velocity variance, skewness, and kurtosis. The ARM Facility currently operates several scanning coherent Doppler lidar systems at various sites around the globe. These instruments operate in the near infrared and provide measurements of radial velocity, attenuated aerosol backscatter, and signal-to-noise ratio. Previously shared…
