This new release of the ARM-Diags extended to include the metrics and diagnostics on the land-atmosphere (L-A) coupling. Specifically, basic statistical metrics on the diurnal cycles of surface sensible and latent heat fluxes, planetary boundary layer (PBL) and lifting condensation level (LCL) currently available at the ARM Southern Great Plains (SGP) site have been added. The two-legged metrics evaluating the strength of L-A coupling by partitioning the impact of the land states on surface fluxes (the land leg) and from the impact of surface fluxes on the atmospheric states (the atmospheric leg) are also added. The inclusion of metrics on the L-A coupling enables quick evaluation of model simulated L-A coupling processes against the ARM ground-based observations.
