SACR ADVance Quasi-Vertical Profile Evaluation Product Released

Published: 17 April 2017

Data Announcements

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 important signatures in ice and mixed-phase clouds. SACR-ADV-QVPs are produced using a sequence of [...]

ARM Data Discovery Tool Provides New Data Delivery Methods

Published: 11 April 2017

Data Announcements, Facility News

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 terabytes (TB) to 25 TB per month. Responding to an increase in the volume of data requests, the ARM [...]

Multi-Angle Snowflake Camera Value-Added Product Now Available

Published: 19 March 2017

Data Announcements

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 centimeters away within a 20-centimeter wide ring through which hydrometeors fall. Located immediately above [...]

Two New Data Products Available from the Radar Wind Profiler

Two New Data Products Available from the Radar Wind Profiler

Published: 19 March 2017

Data Announcements

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 further used to retrieve boundary layer winds. The retrieved winds are often used for forcing model [...]

New Release of Radar CFAD Data Product for ARM Radar Simulator

New Release of Radar CFAD Data Product for ARM Radar Simulator

Published: 15 February 2017

Data Announcements

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 has been removed due to a radar calibration issue. An ARM cloud radar simulator was developed to [...]

New WACR Radar Data Available for AWARE Campaign

Published: 16 November 2016

Data Announcements

The W-band ARM Cloud Radar-Active Remotely-Sensed Cloud Locations (WACR-ARSCL) provides cloud boundaries and best-estimate time-height fields of radar moments. WACR observations are corrected for velocity aliasing, and then significant detection masks are produced. The corrected WACR measurements are combined with observations from the micropulse lidar, ceilometer, soundings, rain gauge, and [...]
