Weather Logger

About

Simple Python script to log METAR and TAF weather reports from aviation.meteo.fr XML API (AEROWEB) to CSV files.
Since v2.0, can also download WINTEM, TEMSI FRANCE and TEMSI EUROC maps to PDF files. Enjoy !

AEROWEB data are free and provided by Météo-France. You need to complete and sign in triplicate the AEROWEB Server agreement and send it by mail (webmaster . aeroweb AT meteo . fr) and then by post to receive your AEROWEB Server identifier. This is a requirement for this Python script to work.

Usage

Run weather_logger.py with a config.ini file path as -c command line argument, for example from a cron job.

Crontab every 10 minutes ? There you go :

*/10 * * * * cd /SCRIPT_PATH/ && /usr/bin/python3 /SCRIPT_PATH/weather_logger.py -c /CONFIG_PATH/config.ini

⚠️ The cd /SCRIPT_PATH/ command from the example above is MANDATORY in a cron job if you want to use relative paths in your config.ini configuration file. You are welcome.

Output

1. CSV file(s) containing METAR / TAF reports in the following format : YYYY-MM-DD HH:mm METAR_OR_TAF_REPORT

For LFPG ICAO airport code, for example :

• METAR_LFPG.csv :

2018-02-21 16:00 METAR LFPG 211500Z 02011KT 330V110 4500 HZ NSC 05/M02 Q1021 TEMPO6000=
2018-02-22 16:00 METAR LFPG 220800Z 03014KT 010V090 3000 BR NSC M02/M04 Q1019 NOSIG=

• TAF_LFPG.csv :

2018-02-21 16:00 TAF AMD LFPG 211306Z 2113/2218 03012KT 4000 HZ BKN020 TEMPO 2113/2117 6000 BECMG 2202/2204 4000 BR BKN005 BECMG 2207/2209 5000 NSW SCT010BECMG 2212/2214 SCT025 TX06/2115Z TNM03/2206Z=
2018-02-22 16:00 TAF AMD LFPG 220719Z 2207/2312 03010G20KT 5000 BR NSC TEMPO 2207/2210 3000 BR TEMPO 2210/2218 4500 HZ TX04/2215Z TNM03/2306Z=

2. PDF file(s) for WINTEM, TEMSI FRANCE and TEMSI EUROC maps :

• EUROC_0.pdf
• EUROC_1.pdf
• TEMSI_0.pdf
• WINTEM_0.pdf

Requirements

• Python 3
  • lxml
