The three precipitation datasets are indeed in reasonable agreement over the polar stereographic domains, but less consistent over the tropical regions of Africa and South America identified previously, even though there is a fair degree
of qualitative agreement between ERA - Interim and JRA - 55 for anomalies in oceanic precipitation in the tropics.
Contributors to this final summary for 2012 are
in qualitative agreement with NSIDC statement; short excerpted statements are below, and the full individual contributions are available as PDFs at the bottom of this page.
Atmosphere - Ocean General Circulation Models also tend to simulate less intense ENSO events, in
qualitative agreement with data, although there are large differences in magnitude and proposed mechanisms, and inconsistent responses of the associated teleconnections (Otto - Bliesner, 1999; Liu et al., 2000; Kitoh and Murakami, 2002; Otto - Bliesner et al., 2003).
These results are in
qualitative agreement with the theoretical prediction of dynamical scaling.
Estimates from adjusted radiosondes, satellites (MSU channel 4) and reanalyses are in
qualitative agreement, suggesting a lower - stratospheric cooling of between 0.3 °C and 0.6 °C per decade since 1979.
We still find that the brightness ratio between 70 and 160 microns shows a marginal sign of the central excess, in
qualitative agreement with the ISO result.
