ARM Produces Its First 3-Dimensional Large-Scale Forcing Data
This schematic showing ARM’s Southern Great Plains atmospheric observatory illustrates the difference between VARANAL and VARANAL3D. The Atmospheric Radiation Measurement (ARM) user facility has made available its first three-dimensional (3D) large-scale forcing data using a 3D constrained variational analysis approach, known as VARANAL3D. Initially, VARANAL3D evaluation data are available from two field campaigns at ARM’s…
