Problem
We want to access G5NR data by downloading files by ftp/wget.
Solution
The base url for G5NR data is
ftp://G5NR@ftp.nccs.nasa.gov/c1440_NR/DATA
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
ftp://G5NR@ftp.nccs.nasa.gov/c1440_NR/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 as
wget ftp://G5NR:@ftp.nccs.nasa.gov/c1440_NR/DATA/0.5000_deg/inst/inst01hr_3d_T_Cv/Y2006/M09/D18/*
The * at the end would retrieve all (24) files for the given day.
To download a file for a specific time, say 0900z, we can use
wget ftp://G5NR:@ftp.nccs.nasa.gov/c1440_NR/DATA/0.5000_deg/inst/inst01hr_3d_T_Cv/Y2006/M09/D18/c1440_NR.inst01hr_3d_
