| hasSummary |
-
The 5-degree latitude/longitude grids contained in this dataset make
up the longest continuous set of daily gridded Northern Hemisphere
sea-level pressure data in the DSS archive. These grids have been
assembled by DSS from the grids of various meteorological chart
digitization projects and operational analyses
[http://rda.ucar.edu/datasets/ds010.0/docs/data_sources.php]. Grids
begin in 1899 and cover the Northern Hemisphere from 15N to the
North Pole. The dataset continues to be updated regularly as new
data become available.
In the earlier years, there is one grid per day, but from July 1962
on, there are two grids per day. Prior to 1946, the original grids
had a 10-degree resolution and the intermediate points were
interpolated and indicated as such. Also in this period, there are
times when large numbers of gridpoints are missing, particularly
over the Asian continent. For more information, see the
documentation [http://rda.ucar.edu/datasets/ds010.0/docs/] about
original data points.
