ds010.0 - Daily (and Monthly) Northern Hemisphere Sea Level Pressure Grids,

continuing from 1899

This free dataset contains time-series collections of daily,monthly, and seasonal

gridded Northern

Hemisphere sea-level pressure data on a 5-degree (72x15) latitude/longitude

grid.These grids have

been assembled from the grids of various operational models and meteorological

projects.For monthly

grids, it is preferable to use the grids in ds010.1

(http://dss.ucar.edu/datasets/ds010.1), which

have undergone some extensive corrections.

Sources for DS010.0 - Sea Level Pressure, 1899 - current, twice daily

Data in this collections were assembled by the Data Support Section of

the Scientific Computer Division, National Center for Atmospheric Research

from several sources.

PERIOD DATA SOURCE

Jan 1899 - Jun 1939 NWS Extended Forecast Division digitized from

from historical charts and QC work was done

by NOAA ERL.

Jul 1939 - Nov 1944 Digitized by MIT from historical charts received

from the Extended Forecast Lab.

Dec 1944 - Dec 1945 no data

Jan 1946 - Mar 1955 Digitized at National Climatic Data Center

under a Navy contract from historical weather charts.

Apr 1955 - Mar 1960 Points were hand read from historical charts

by the 433L ESSPO Project.

Apr 1960 - jun 1962 Digitzed under at National Climatic Data Center

under a Navy contract from historical weather charts.

Jul 1962 - Dec 1993 Operational analyses from US Navy, Monterey

with a few gaps filled by NCEP analyses.

Jan 1994 - current NCEP operational final (FNL) analyses. 

More details on sources of data.

Grids from historical maps, Jan 1899 - Jun 1939 (13Z):

This data, originated at the National Climatic Center, Asheville,

N.C., was sent to the Extended Forecast Lab; from where a copy

was sent to the NOAA Environmental Research Laboratories. There,

Mr. Cotton and others spent about 1.5 man years comparing each

point to the average of surrounding values. They checked each

difference over 10 mb with the original maps to see whether a

correction was necessary. Errors greater than 10 mb were likely

discovered and corrected by this process. Data are missing where

historical maps could not be analyzed. Eastern Russia (40-80N,

35-150E) is missing for 1916-1920, for 3 months in 1921, for one

month each in 1922 and 1931, and for 6 months each in 1938 and 1939.

The grids were on a diamond lat-lon grid (5-degree lat, 10-degree

lon), 20N-80N, with no data at 75N. There are no pole values.

Grids from MIT, Jul 1939 - Nov 1944 (12Z):

MIT read values from charts from the Extended Forecast Lab. The

data are for each 5 degrees of latitude and even 10 degrees of

longitude for 15N-80N. Data for 85N is present for 10 days.

Grids from Navy*, Jan 1946 - Mar 1955 (12Z), Apr 1960 - Jun 1962 (12Z),

Jul 1962 - current (00Z,12Z):

The grids from the historical series maps for Jan 1946 - Mar 1955, and

Apr 1960 - Jun 1962 were digitized with a curve follower at NCC under

Navy contract. These data were then analyzed by the Navy's operational

objective analysis program that is used on current data. These grids

include manual bogus to put in tropical storms. There is no data at 15N.

* Although the Navy grids are the primary source for updating this set,

occasionally grids from the National Meteorological Center are used

until the Navy grids are received.

- 2 -

Grids from the 433L ESSPO Project, Apr 1955 - Mar 1960 (00Z,12Z):

Data for every other point in the NMC octagonal grid were manually

read from charts for this period. There is no data at 15N.
