Highlights from DOE Scientific User Facility at AGU Fall Meeting 2009
Scientists from around the world use data from the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Climate Research Facility to study the interactions between clouds, aerosol, and radiation. At this year’s American Geophysical Union (AGU) Fall Meeting, scientists will present oral and poster sessions of their research using these data for long-term analyses, model…

Thumbs-Up for Radar Design Reviews—Key Recovery Act Milestone
In November, ARM completed a series of successful preliminary design reviews for new scanning cloud and precipitation radars. This progress marks a key milestone for deploying 18 new radars—unheard of in the climate research arena—throughout the user facility through funding from the American Recovery and Reinvestment Act.

ARM Joins Global Reference Upper-Air Network
One of the largest challenges from a global climate observations perspective is a lack of accurate water vapor measurements in the upper troposphere and lower stratosphere. The Global Climate Observing System (GCOS) Reference Upper Air Network (GRUAN) is an international reference observing network designed to meet climate requirements and fill this major void. In 2009,…

Spectroradiometer Completes Field Campaign at North Slope
In October, researchers funded by the National Science Foundation completed a six-month redeployment of the Analytical Spectral Devices (ASD) shortwave spectroradiometer at the ARM North Slope of Alaska site in Barrow. Each minute, the ASD instrument automatically records spectra in the wavelength range 350-2200 nm, which encompasses most of the sun’s energy. Measurements from the…

Updated Evaluation Product Available for Calculating Surface Spectral Albedo
An updated version of the Surface Spectral Albedo (SurfSpecAlb1Mlawer) value-added product (VAP) has been released as an Evaluation Product for the Southern Great Plains (SGP) site. The original version of the algorithm created a near-continuous best estimate of broadband and narrowband downwelling irradiance, upwelling irradiances, and surface albedo using the multi-filter radiometers (MFRs) on the…

Happy New (fiscal) Year! Cloud Droplet Probe Arrives in Time for SPARTICUS
Kicking off the new fiscal year, on October 1 the ARM Aerial Facility received the first component – a cloud droplet probe (CDP) – of many new aircraft research instruments that will arrive in the coming year through funding from the American Recovery and Reinvestment Act. Designed to measure the size distribution of cloud particles,…

New 3-Channel Microwave Radiometer Deployed at Southern Great Plains Site
Throughout ARM, measurements of precipitable water vapor and liquid water path are provided by microwave radiometers. These measurements are essential for improving scientific understanding of clouds and how they are represented in climate models. In late September, ARM added the latest generation microwave radiometer technology at its Southern Great Plains site. The increased capabilities and…

Scanning Capability Added to Cloud Radar
As a prelude to great things to come throughout the user facility, a new 95-gigahertz scanning W-band cloud radar was installed in late September at the ARM Mobile Facility deployment site in the Azores. This new radar joins the instrument suite that has been collecting data at the airport on Graciosa Island since May 2009.…
