Missing Data:
- Quoting ECMWF newsletter of 27 March 1997 from NCAR:
"Missing fields in reanalyses
In ds115.0 (the surface analyses), total column water (parameter 136) is not available from 1 September 1980 through 31 December 1981. This field was not introduced into the processing until January 1982, but the period from 1 January 1979 to 31 August 1980 was re-processed and this field was produced during this re-run.
In ds115.2 (the supplementary fields), downward surface solar and thermal radiation (parameters 169 and 175) are not available from 1 September 1980 through December 1982 for similar reasons. These fields were not included in the post-processing for reanalysis production until January 1983."
