NCEP Reanalysis Temperature

Summary

Gridded daily time step data from Ohio State University based on NCEP/NCAR reanalysis data, interpolated from the NCEP/NCAR grids (~209km) (http://www.ncep.noaa.gov/) to the 25km Northern Hemisphere EASE-Grid using a bi-lagrange interpolation formula. As part of the data processing of ArcticRIMS (http://RIMS.unh.edu) based at the Water Systems Analysis Group, University of New Hampshire all data sets have been aggregated to multiple temporal and spatial resolutions.

The data is presented in 24 sub-datasets of different spatial and temporal aggregations (see aggregation description below).

Data Access

ORDER data for delivery by FTP.

* - This Dataset was submitted to or acquired by ArcticRIMS from a third party Research Institution.

Data Aggregation

There are two distinct methods to produce data aggregation along the "time" axis of the cube. These are -

1. Mean. Monthly or yearly values for each grid cell in the dataset has been produced as simple mean (average) over the indicated time period. An example is temperature datasets.

2. Sum. Monthly or yearly values for each grid cell in the dataset has been produced as arithmetic total over the indicated time period. An example is precipitation datasets.

3. Vector. Monthly or yearly values for each grid cell in the dataset has been produced as product vector (vector average) over the indicated time period. An example is wind direction datasets.

4. Class. Monthly or yearly values for each grid cell in the dataset has been produced as prevailing (most frequent) qualitative class over the indicated time period. An example is freeze-thaw datasets.

Each aggregated data file in a dataset has a notation of a method (mean or sum) used to produce the file. The notation included in the first (top) line of the file. Please, pay attention to that.

Aggregation along the "spatial scale" axis of the cube is done using simple mean (average) over all grid cells of each basin (river, sea basin, or continent) from an appropriate grid cell file.
