Practice: GPM

GPM is a precipitation monitoring satellite of JAXA and NASA. Let's practice how to get and open it!

THOR is an application software which let you view TRMM and GPM data easily. It's free. You can install it to Linux

https://arthurhou.pps.eosdis.nasa.gov/thorrelease.html

You can install it to Ubuntu Linux 20.04 like this:

mkdir ~/work_THOR
cd ~/work_THOR
wget http://archive.ubuntu.com/ubuntu/pool/main/g/glibc/multiarch-support_2.27-3ubuntu1.6_amd64.deb
sudo dpkg -i multiarch-support_2.27-3ubuntu1.6_amd64.deb
wget -c http://ftp.debian.org/debian/pool/main/libx/libxp/libxp6_1.0.2-2_amd64.deb
sudo dpkg -i libxp6_1.0.2-2_amd64.deb
wget https://pps.gsfc.nasa.gov/THOR/version_2.2/THOR_2.2_linux.zip
unzip THOR_2.2_linux.zip
cd orbit
./setupUNIX.sh
vi orbitUNIX.sh
(rewrite #!/bin/sh to #!/bin/bash)
./orbinUNIX.sh -e
(exit)

GPM data are free. You can get them at G-Portal site of JAXA.

First, you should get an account (user ID and password) of G-Portal.

Then you try this on your Ubuntu 20.04.

$ mkdir ~/work_GPM
$ cd ~/work_GPM
# Suppose your username is xxxxxxxx
$ sftp -oPort=2051 xxxxxxxx@ftp.gportal.jaxa.jp
xxxxxxxx@ftp.gportal.jaxa.jp's password: 
Connected to ftp.gportal.jaxa.jp.
