In particular, at the DOI 10.6069/h5vd6wc0 gridded data for the "offline" experiment corresponds to equivalent experiments in Hakim et al. (2016). Note that Perkins and Hakim (2017) pertains to "online" data assimilation, and we do not currently plan to use that method for the final version of the LMR.

If you only want a list of LMR values for Northern Hemisphere 2m air temperature, see the red-font link below for Figure 2.
