Comantario (en inglés):

NCAR has world monthly surface station climatological data for over 4700
different stations (2600 in more recent years) up through 2003.  Data for
some stations goes as far back as the mid-1700's.  ....
Most of the data was obtained directly from
the National Climatic Data Center (NCDC), Asheville, North Carolina.
However, much of the data prior to 1951 came from John Wolbach of Harvard
College Observatory, who contracted to have this data punched at NCDC.
The first six months of 1961 were punched at NCAR.  Sharon Nicholson,
Florida State University, provided African precipitation data to extend
the records of over 250 stations. (For any specific use of the African
precipitation data, please credit Sharon Nicholson).  Dennis Shea, NCAR,
has been a valuable source for data obtained directly from various
countries.  The standard parameters
available are sea level pressure, station pressure, temperature, and
precipitation.  After 1960, additional available parameters include
moisture and percent sunshine.

The data through 1973 was scanned for gross format errors in card
punching, and several hundred errors were corrected.  Extreme values were
inspected on the basis of being 4 or 5 standard deviations from the long
period monthly mean.  Many such deviations are real; but some were
obviously the result of card-punching or publication errors, and some
values were so extreme they were set to missing.  Some of the data
received on tape from NCDC overlaps that received on earlier tapes.  These
overlaps are considered to be updates and are merged with or replace the
data previously received.
