Data Announcements

Data sets for ARM Best Estimate 2-dimensional Gridded Surface (ARMBE2DGRID) and ARM Best Estimate Station-based Surface (ARMBESTNS) are available now for year 2015. The primary goal of these two data sets is to provide 2D spatial data of important surface variables to facilitate studies on [...]

A new version of the Python-ARM Radar Toolkit (Py-ART) is available. Py-ART is an open-source software package that helps read, process, and visualize weather radar data. This is the ninth version of Py-ART since it became open source in 2013, meaning anyone can obtain the source code or propose a [...]

The Scanning ARM Cloud Radar ADVance Quasi-Vertical Profile (SACR-ADV-QVP) provides a quasi-vertical representation of azimuthal averaged polarimetric variables such as differential reflectivity, specific differential phase and correlation coefficient, and linear depolarization ratio to reveal [...]

All the data collected through the ARM Climate Research Facility have to go somewhere, but it’s not easy to pack them all in—or deliver them from—one spot. Every month, hundreds of users access the ARM Data Archive to download portions of ARM data collections at rates from 20 [...]

The Multi-Angle Snowflake Camera (MASC) instrument provides high-resolution multi-angle imaging of hydrometeors in free fall with simultaneous measurement of fall speed. The MASC consists of three cameras, separated by 36 degrees, each pointing at an identical focal point approximately 10 [...]

The Radar Wind Profiler (RWP) records the full Doppler spectrum in a wind mode and a precipitation mode. The data from the wind mode are used to calculate the first three moments of the Doppler spectrum (reflectivity, mean Doppler velocity, and spectrum width) with the mean Doppler velocity [...]

Updated: Newly released data are now included from the Southern Great Plains, North Slope of Alaska, and the Tropical Western Pacific atmospheric observatories from 2011 to 2013. Previous radar CFAD data (nsaradarcfadC1.c1) for the period between 2006 and 2010 from the North Slope observatory [...]

Researchers supported by the U.S. Department of Energy’s Atmospheric System Research (ASR) program are interested in studying land-atmosphere interactions at the meso-scale level around the ARM Southern Great Plains (SGP) atmospheric observatory. In order to help address these research [...]

Updated: Data are now available for the Southern Great Plains atmospheric observatory for the years 2013 and 2014. Version 2 of the continuous large-scale forcing data value-added product known as VARANAL for the Southern Great Plains (SGP) atmospheric observatory has been released for [...]

Updated: Data are now available for the Southern Great Plains atmospheric observatory for the years 2013 and 2014. The ARM Best Estimate 2-dimensional Gridded Surface (ARMBE2DGRID) and ARM Best Estimate Station-based Surface (ARMBESTNS) data sets have been updated to include data for year [...]
