New Synthetic Microwave Sounding Unit (MSU) Datasets 2011,
Developed using Method by C. Mears, 2011
The details of the datasets are described in the 'Supporting Material'.Potential users should download and read this document before downloading the datasets. No additional documentation nor additional support for these data can be provided.
The data was developed using a new method by Carl Mears at Remote Sensing Systems in Santa Rosa, California, and is documented in a scientific paper currently under review at the Journal of Atmospheric and Oceanic Technology
Mears, C.A., B.D. Santer, C.S. Doutriaux, and F.J. Wentz, 2011: Calculating synthetic microwave sounder brightness temperatures from discrete-level data. Journal of Atmospheric and Oceanic Technology (in review).
Publications using any or all of the synthetic MSU T2 temperatures and/or the synthetic T2LT temperatures should reference these datasets as follows:

2011 MSU temperature data:
"TLT_picntrl.tar" contains time series of monthly-mean lower
tropospheric temperature anomalies from the 29 CMIP-3 pre-industrial
control runs described in Table S3 of the document appended to this
email [this document is the online "Supporting Material" for Santer et
"TLT_ex20c3m.tar" contains time series of monthly-mean lower
tropospheric temperature anomalies from the 51 CMIP-3 simulations of
historical climate change (the spliced 20CEN/SRES A1B simulations).
These runs are described in Table S2 of the appended document.
All synthetic MSU temperature data in "TLT_picntrl.tar" and
"TLT_ex20c3m.tar" were spatially-averaged over 82.5 degrees N to 70
The third tar file "SST_ex20c3m.tar" contains the CMIP-3 sea-surface temperature (SST)
data used for producing Figure 10 in Santer et al. (2011).
"SST_ex20c3m.tar" consists of time series of monthly-mean SST anomalies
from 50 CMIP-3 simulations of historical climate change (the 51 spliced
20CEN/SRES A1B simulations in Table S2, minus the ncar_pcm_run2, which
begins in 1961, and does not cover the full 1947-2010 period used for
analyzing SST data). All SST data in "SST_ex20c3m.tar" were
spatially-averaged over 50 degrees N to 50 degrees S.
