adcme > ARM Diagnostics for Climate Model EvaluationData Source Type(s) > PI

A Python-based diagnostics package is currently being developed by the ARM Infrastructure Team to facilitate the use of long-term high-frequency measurements from the ARM program in evaluating the regional climate simulation of clouds, radiation, and precipitation. This diagnostics package computes climatological means of targeted climate model simulation and generates tables and plots for comparing the model simulation with ARM observational data. The CMIP model data sets are also included in the package to enable model inter-comparison. The ARM observational data constitute the core content of the diagnostics package. These data products include two types of data sets: 1. Observational data: we use long-term data sets available at SGP, NSA, TWP, ENA, and MAO to build representative climatology. 2. CMIP5 and CMIP6 climate model simulation data sets: these are auxiliary data sets for climate model evaluation.

The Python-based diagnostics package is available at:


This data set serves as part of the ARM data-oriented diagnostics package (ARMDIAG) for climate model simulations. The data were prepared for facilitating the use of ARM data sets in climate model evaluation. The data were collected from multiple ARM instrument data streams and VAP data streams. Please refer to table 1 in the technical reports. The data sets will be updated as needed (i.e., update of original data stream, new data available, adding more sites). Detailed information about this data set is available in the technical report available at
