Multi-Model Large Ensemble Archive (MMLEA) Version 2

The MMLEA Version 2 is an extension of the MMLEA Version 1, now including 18 models, 15 two-dimensional variables, and a suite of observational data sets. Data in this archive has been remapped to a common 2.5 x 2.5 degree grid for ease of inter-model comparison. Data will be made available via the NCAR Research Data Archive and NCAR's casper system. 

The table below provides a summary of the salient characteristics of the models and simulations contained within the archive. Further discussion of the utility and applications of the archive is given in the reference below. Please direct questions about this archive to Dr. Nicola Maher [nicola.maher@anu.edu.au] or Dr. Clara Deser [cdeser@ucar.edu], and direct questions about the CVDP comparisons to Adam Phillips [asphilli@ucar.edu].

We kindly ask that you reference Maher et al. (2024) when presenting results based on the Multi-Model Large Ensemble Archive version 2 in either oral or written form. We also ask that the appropriate references from the table below (for each model used) are cited when using the MMLEAv2 data.

MMLEAv2 data are expected to be posted by early February 2025. 

Climate Variability Diagnostics Package v6 comparison images and data are available in Table 1 below, a summary of all model data is included in Table 2 below, and a summary of all available observational data is included in Table 3 below.

Variables within the archive (all monthly): sst/tos, zos, pr, psl, tas, tauu, tauv, zg500, sos, evspsbl, mlotst, TXx (monthly maximum dailymaxtas), TNn (monthly minimum dailymintas), Rx1day (monthly maximum pr) and siconc/sic.
