Back to G5NR Data Access Guide.
Problem
We want to access G5NR data by downloading files from the https server using either a web browser or the command line tool wget.
Solution
The base url for G5NR data is
https://g5nr.nccs.nasa.gov/data/
At this location, the data is organized by resolution (0.5000_deg/0.0625_deg), type (const/inst/tavg/tdav), collection name, year, month and day as follows:
DATA |---resolution | |---type | | |---collection | | | |---year | | | | |---month | | | | | |---day
For a discussion about the available resolutions, types and collections, please see File:G5NR-Ganymed-7km FileSpec-ON6-V1.0.pdf.
Download using a web browser
A web browser can be used to browse directories, read and retrieve files. To retrieve the collection inst01hr_3d_T_Cv for the day 2006-09-18, one needs to point to
https://g5nr.nccs.nasa.gov/data/DATA/0.5000_deg/inst/inst01hr_3d_T_Cv/Y2006/M09/D18.
At this location, a file may be downloaded by simply clicking on the file name.
Download file(s) using the command line tool wget
The command line tool wget can be used to retrieve the same files. To download a file for a specific time, say 0900z, we can use
wget https://g5nr.nccs.nasa.gov/data/DATA/0.5000_deg/inst/inst01hr_3d_T_Cv/Y2006/M09/D18/c1440_NR.inst01hr_3d_T_Cv.20060918_0900z.nc4
