New Addition to the Climate Modeling Best Estimate Data Set
A new addition to the Climate Modeling Best Estimate (CBME) data set has been released, comprising a statistical summary of the CMBE data. It includes both monthly mean and monthly mean diurnal cycle and their climatologies for all the geophysical quantities contained in the CMBE data sets. The CMBE data set is specifically tailored for…

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…

New Release of Cloud Modeling Best Estimate Data Set
Detailed observations of clouds and radiation, along with the associated large-scale conditions such as temperature and relative humidity profiles, surface precipitation, and sensible and latent heat fluxes, provide invaluable information to understand the structure and temporal variability of observed cloud systems. All these variables are now conveniently packaged into the latest release of the Climate…

Shortwave Flux Analysis Extended to North Slope of Alaska
This summer, the ARM Radiative Processes Working Group released an extension of the Shortwave Flux Analysis value-added product to include data from the ARM North Slope of Alaska locale. Originally released in 2004, the Shortwave Flux Analysis VAP was developed to infer clear-sky shortwave, shortwave cloud effects, and fractional sky cover from shortwave measurements at…

Data Plots Available for the ARM Mobile Facility Deployment in the Azores
The 20-month deployment of the ARM Mobile Facility on Graciosa Island in the Azores is well underway in support of the Clouds, Aerosol, and Precipitation in the Marine Boundary Layer field campaign. Data are being collected to study the seasonal life cycle of marine clouds and how they modulate the global climate system. These data…

Best Estimate Data Available for Sensible and Latent Heat Fluxes at the SGP
Data from the Bulk Aerodynamic Energy Balance Bowen Ratio (EBBR) Station, or BAEBBR, Value-Added Product (VAP) are now available at the ARCF Data Archive for the period 1993 through 2008 at the 15 Southern Great Plains (SGP) extended facilities with EBBR measurements. The BAEBBR VAP produces a “best estimate” of sensible and latent heat fluxes…

Upgrades to Cloud Radar Lead to New Data Product: MicroARSCL
By providing detailed information about cloud properties, the millimeter wave cloud radar (MMCR) is a key capability at ARM sites. Between 2004 and 2006, ARM completed upgrades to the digital portion of the MMCR receivers. These upgrades significantly improved the radar’s temporal resolution, extended the interval for detecting velocity, and allowed continuous recording of Doppler…

Data Available from ARM Mobile Facility Deployment in China
The Study of Aerosol Indirect Effects in China was anchored by the ARM Mobile Facility in Shouxian and included an additional instrumented site to the east at Lake Taihu and two instrumented sites to the north. All data collected by the ARM Mobile Facility in Shouxian are now publicly available at the Data Archive. In…

Radiative Transfer Model Intercomparison Project Data Now Available
The ARM Climate Research Facility Data Archive has published the Radiative Transfer Model Intercomparison Project (RTMIP) data set, compiled by Bill Collins. This data set compares the radiation models embedded in the Atmosphere-Ocean General Circulation Models used in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change. These radiation models were compared to…

Second Version of Long-Term Climate Modeling Best Estimate Data Released
Version 2 of the Climate Modeling Best Estimate includes the data source information for cloud fraction, as depicted in this data plot. With major improvements in the cloud fraction, cloud liquid water path (LWP), precipitable water vapor (PWV), and surface radiative fluxes, a new version of the “Climate Modeling Best Estimate” (CMBE) is now available…
