README
This is a commandline tool to plot global temperature data using data from the Global Historical Climatology Network.
See https://www.ncei.noaa.gov/pub/data/ghcn/v4
Installation
============
To compile from source first install the prerequisites:
On a Debian based system:
``` bash
sudo apt-get install build-essential gnuplot wget marble python3
```
On Arch/Parabola:
``` bash
sudo pacman -S gnuplot wget marble python
```
Obtaining the data
==================
Before you begin you'll need to download the latest version of the GHCN version 4 data. tempgraph needs three files: the country codes, the weather stations and the temperature data itself. These files can be obtained here:
```bash
mkdir data
cd data
wget https://www.ncei.noaa.gov/pub/data/ghcn/v4/ghcnm.tavg.latest.qcf.tar.gz
wget https://www.ncei.noaa.gov/pub/data/ghcn/v4/ghcnm-countries.txt
tar -xzvf ghcnm.tavg.latest.qcf.tar.gz
cd ..
```
The compressed archive contains two files, one which is the temperature data (.dat) and the other which contains details of the weather stations (.inv). I typically rename these to:
```bash
cp data/ghcnm.v4*/*.dat data/v4.mean
cp data/ghcnm.v4*/*.inv data/wmo.txt
cp data/ghcnm-countries.txt data/v4.country.codes
```
Usage
=====
``` bash
python3 tempgraph2.py
ls *.kml *.jpg
```
