CRTF Telecon - 06-24-2015

Dear Greg, Thank you again for the great presentation. Really exciting results. We might want to discuss how you are using CE to compare the 20CR to NASA GISTEMP in some detail. As one note, some versions of GISTEMP and 20CR version 2 use HadISST1.1 over the oceans through 1982 (or 1983 - not sure when GISTEMP switches). So, they should agree almost perfectly for that period. You may want to also compare with the new 20CR version "2c" , which has an 18 member ensemble of pentad Simple Ocean Data Assimilation with sparse observation input (SODAsi.2, Giese et al. 2015, in review) as the specified SSTs. Over land, at least for trends 1901-2010, you can see in Compo et al., GRL, 2013, dx.doi.org/10.1002/grl.50425 Supporting Information Compoetal_GRL_AuxiliaryMaterial_final.pdf Table S2, the 20CR (version 2) compares the worst with GISTEMP at either smoothing. best wishes, gil

Hi Gil,
One of my students is working on assessing reanalyzed clouds and radiation budgets using NASA satellite results, and we should get some results in next a couple of months. However, I will most likely on travel during Late June for IUGG meeting. So is it possible for us to present our results during May (i.e. switch Arctic topic into May?)

Thanks,
Xiquan

I would like to give a 20-min talk on "Air-sea fluxes in the marginal sea-ice zone: Atmosphere reanalyses versus the ship observations"
