2. Data at 24 observation points adjacent to the NSR
3. Data compiled for use in the NSR operation simulation described in Section 4.4
The content of the data can be categorized as follows.
a. Ice concentration
For each type of ice (first-year ice, multi-year ice, etc.), statistics of average, maximum and minimum values, etc. are stored as percentile or decile values.
b. Ice thickness
Statistics of average, maximum and minimum values, etc. are registered
c. Frequency of ice ridges
The number of ice ridges per 1km of distance is stored (in data source type 3 only).
d. Size of pack ice
The sizes of pack ice are registered (in data source type 3 only).
[3] Meteorological data
The following meteorological data is in storage.
a. Air pressure data
Observation data of the US National Center of Atmospheric Research from 1964 to 1989 and of the Hydrometeorological Center of Russia from 1989 to 1994 are registered. A total of 384 data points were settled for a wide area covering 40°-210°E and 60°-85°N.
b. Air temperature data
These data are based on AARI data from an area 40°-210°E and 60°-85°N.
