The Atmospheric Radiation Measurement (ARM) user facility provides tailored datastreams known as ARM Best Estimate (ARMBE) data products for use in the evaluation of global earth system models. ARMBE data sets are now available for the Radiative Divergence Using AMF, GERB, and AMMA Stations (RADAGAST) field campaign in Niamey, Niger, and the ARM West Antarctic Radiation Experiment (AWARE).
The data sets available for both campaigns are ARM Best Estimate Atmospheric Measurements (ARMBEATM) and ARM Best Estimate Cloud Radiation (ARMBECLDRAD). ARMBEATM contains basic atmospheric quantities, and ARMBECLDRAD provides cloud and radiation quantities.
An ARMBE product assembles quantities that are both well observed by ARM over many years and are often used in model evaluation into one data set. These products consist of hourly averages and thus have temporal resolution comparable to a typical resolution used in earth system model output.
Scientists can use the RADAGAST and AWARE ARMBE data sets now. Data for RADAGAST are available from January 1 to December 30, 2006. The AWARE data are from January 1 to December 31, 2016, at McMurdo Station, Antarctica.
Find more information about ARMBE data products on the ARMBE web page and Xie et al. (2010).

Feedback and use of the ARMBE data are always welcomed. If you have questions or suggestions about the RADAGAST/AWARE data, please contact Yuying Zhang or Shaocheng Xie.
Users can access the ARMBEATM and ARMBECLDRAD data sets from the ARM Data Center. (Go here to create an account to download the data.)
