New Best Estimate Data Available for WACR-ARSCL
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, this VAP uses observations from the micropulse lidar and ceilometer to produce cloud boundaries and time-height profiles of cloud…

Testbed Workshop to Improve Climate Models
A primary goal of DOE’s Earth and Environmental Systems Sciences Division (EESSD) is to expand the predictive ability of regional and global climate models (GCMs). As climate models are developed, testbeds are one set of tools used to understand, evaluate, and identify areas of improvement. A recently completed report summarizes the results of a DOE…

Forcing Data for MC3E Updated
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 dry bias correction. These include both the ensemble forcing, which is based on uncertainties in precipitation, and the multi-domain forcing data sets over the 300 km, 150 km, and 75…

Ceilometer Derived Planetary Boundary Layer Height Datastream Available
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 scientific community thanks to an evaluation conducted to compare the PBL height measurement from…

A Disappearing Act? Researchers Investigate Tropical Ozone
Massive storm clouds that form in tropical regions can generate heat and energy—convection—that drive air currents around the globe. This is especially true for the area known as the “Tropical Warm Pool” in the western Pacific Ocean and eastern Indian Ocean. In this region, convection drives air into the stratosphere as part of the global…
