2D ARM Best Estimate Data Sets Updated to Include QCECOR

Published: 15 February 2017

Updated: Data are now available for the Southern Great Plains atmospheric observatory for the years 2013 and 2014.

The ARM Best Estimate 2-dimensional Gridded Surface (ARMBE2DGRID) and ARM Best Estimate Station-based Surface (ARMBESTNS) data sets have been updated to include data for years 2011 to 2014.

The ARMBE2DGRID data set merges key surface measurements at the Southern Great Plains (SGP) atmospheric observatory and interpolates—estimates values between two known values—the data to a regular 2D grid to facilitate data application. Data from the original site locations can be found in the ARMBESTNS data set.

The primary goal of these two data sets is to provide 2D spatial data of important surface variables to facilitate studies on precipitation, clouds, and radiation, which require high spatial and temporal observations. In this new release, the input turbulence fluxes from eddy correlation flux measurement (ECOR) are replaced by recently available Quality Controlled Eddy Correlation Flux Measurement (QCECOR). The team is working on expanding these data sets to longer periods.

Feedback and use of the data are welcomed and encouraged. For questions or to report data problems, please contact Qi Tang or Shaocheng Xie. To access both data sets, please browse the ARM Data Archive. (Go here to create an account to download the data.)
