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. Two ARMBE data sets are now available from the Green Ocean Amazon (GoAmazon2014/15) field campaign in Brazil. The ARM Best Estimate Atmospheric Measurements (ARMBEATM) data set contains basic atmospheric quantities, and ARM Best Estimate Cloud Radiation (ARMBECLDRAD) provides cloud and radiation quantities.

These products contain best estimates of several quantities that are often used in model evaluation. The ARMBE data sets from GoAmazon, an ARM Mobile Facility campaign, share the algorithms used for ARMBEATM and ARMBECLDRAD releases from fixed ARM observatories.

Scientists can use the GoAmazon ARMBEATM and ARMBECLDRAD data sets now. Find more information about ARMBE data products on the ARMBE web page.

Feedback and use of the data are always welcomed. If you have questions/suggestions, please contact Shuaiqi Tang or Shaocheng Xie.

Users can access the GoAmazon data sets for ARMBEATM and ARMBECLDRAD in the ARM Data Center. (Go here to create an account to download the data.)
