2D Best Estimate Data Sets From MC3E Now Available
Data sets for the ARM Best Estimate 2-Dimensional Grid (ARMBE2DGRID) and Station-based Surface (ARMBESTNS) are now available for the Midlatitude Continental Convective Clouds Experiment (MC3E) period, which occurred during April to June 2011. The primary goal of these two data sets is to provide 2-dimensional (2D) spatial data of important surface variables to facilitate studies…

Large-Scale Forcing Data from the R/V Roger Revelle
Constrained variational analysis forcing data centered at the R/V Roger Revelle are now available for the Dynamics of the Madden-Julian Oscillation (DYNAMO) and the ARM Madden-Julian Oscillation [MJO] Investigation Experiment [AMIE] on Gan Island, or AMIE-Gan field campaign. Due to the lack of a sounding array on the Revelle, these forcing data were developed based…

High-Vertical Resolution Soundings Available for SGP and NSA
The ARM External Data Center (XDC) now provides atmospheric soundings—vertical measurements of the atmospheric column—in 1-second resolutions collected by the National Weather Service (NWS) in netCDF format to the ARM Data Archive. Quality control is added by the University Corporation for Atmospheric Research. These weather balloon soundings record temperature, pressure, altitude, humidity, and winds for…

MICROARSCL Evaluation Data Released: Harnessing the Power of Radar Doppler Spectra
Four of the roughly 30 variables provided by MICROARSCL are shown here for a day in Barrow, Alaska. Since 2004, the ARM Climate Research Facility has collected continuous recordings of profiling radar Doppler spectra. These recorded spectra offer a powerful means for overcoming the dependency of radar measurements on particle size (proportional to the sixth…

New Best Estimate Data Available for WACR-ARSCL
A data plot from the WACR-ARSCL Reflectivity Best Estimate from Graciosa Island, Azores, is shown for June 27, 2009. New data from the 95 GHz W-band ARM Cloud Radar-Active Remote Sensing of Clouds (WACR-ARSCL) value-added product (VAP) (Kollias and Miller, 2007) are now available in the ARM Data Archive. In addition to the WACR data,…

Forcing Data for MC3E Updated
Multi-scale domains for MC3E, with diameters of 300 km, 150 km, and 75 km. The red triangles denote sounding locations. The green diamonds denote the locations of scanning cloud radars. Large-scale forcing data from the Midlatitude Continental Convective Clouds Experiment (MC3E) have been revised based on the recent update to MC3E sounding data for improved…

Ceilometer Derived Planetary Boundary Layer Height Datastream Available
At the 2012 ASR Science Team Meeting, this comparison received positive feedback from researchers. Planetary Boundary Layer (PBL) height data are now being collected at ARM sites and mobile facilities using an enhanced gradient method algorithm from the Vaisala Ceilometers (VCEIL). These data are part of a new datastream available to the ARM and broader…

ARM Data Archive Registered with Elsevier
Increased visibility via Elsevier’s data repository presents an opportunity to broaden the scientific audience for ARM data. With an ever-increasing need to connect related pieces of information, databases rule the world. As of mid-March, the ARM Data Archive—containing two decades of continuous measurements of clouds, aerosol, precipitation, and radiative energy from ARM sites around the…
