Aside from the possibility of “questionable” stuff from the CRU you quite rightly note that so many other institutions produce independent “similar results”? You suggest this is support that the warming trend identified by the CRU is real.
This is a terrific point and deserves my best effort, so here goes.
The analytical computer applications to process the data are not, as pointed out by Phil Jones, “rocket science”. The only other variables are data and adjustments. The data comes in two forms, “primary” or raw data and “secondary” data which have been modified in some way. The modifications to which secondary data can be subjected are either approved SOA’s (schedules of adjustments) and/or gridded averages. Both sets of secondary data are derived.
There is nothing wrong with derived data providing that the SOA’s are provided to demonstrate “what” was done to the raw data. In the case of gridded averages, any “assumptions” are embedded and therefore independent processing will typically produce a “similar” result.
Each country and their scientific institutions have access to their own countries’ raw temperature data. This does not allow them to arrive at “global” projections. To do this they must access other data, either directly where allowed or via various scientific websites as referred to by Phil Jones. This access can be open, for a fee or only through “affiliation”.
The CRU is not, contrary to popular belief funded by the British, the CRU is funded by the US DOE. Its affiliates are the US research agencies to which you refer. The data they share and merge with their own data is the stuff Phil Jones makes available which is only “gridded” derived averages. (See; Q106, Q107 and Q109) The data that Jones is referring to, that the CRU makes available for sharing “on these other websites” is only “gridded derived” data, no raw data.
