Gridded NORA3 data: automated and remote data extraction
The NORA3 atmosphere hindcast data are remotely accessed using the OPeNDAP framework and the THREDDS Data Server of the Norwegian Meteorological Institute [1]. The data can be extracted for multiple latitudes and longitudes and stored in a gridded format. Atmospheric data are retrieved for seven different heights, from 10 m to 750 m above the surface. The mean wind speed profile can be interpolated using a non-linear scheme based on the Deaves and Harris model [2,3]. Above the ocean, sea roughness is modeled using the Charnock relation. A summary of the NORA3 data and their potential is available in [4]. This code was used to extract the data used in [5].
The getNORA3_subset
function specifically accesses subsets of the NORA3 data (monthly storage), increasing data collection by a factor of x10 or more. However, these subsets do not contain profiles of temperature.
The present submission contains:
-
getNORA3.m
: A function that imports the NORA3 hindcast from [1]. -
getNORA3_subset.m
: A function accessing subsets of NORA3 for enhanced data collection. Note: This subset does not include temperature profiles. -
getz0_charnock.m
: A function estimating sea surface roughness using Charnock's equation and the logarithmic profile of the mean wind speed. -
interpU.m
: A function interpolating the mean wind speed using The Deaves and Harris model [2,3]. -
world.mat
: A data file containing the coastline of countries (used for visualization purposes only). -
Documentation.mlx
: A Matlab LiveScript illustrating how these functions can be used. -
Documentation2.mlx
: A second Matlab LiveScript illustrating how these functions can be used. -
Documentation3-subset.mlx
: A third Matlab LiveScript illustrating getNORA3_subset works. Note that the surface temperature seems a little different here.
Any comments, questions, or suggestions are welcome.
