17 000 weather measurements collected by a weather station created for a college project.

Weather Data

This repo contains weather data collected by a weather station built located in Strasbourg, France by myself and a friend for a class project.

Data

The data was (and still is) collected every 10 minutes between approximately 8 am and 6 pm for the first half and between 1 am and 11 pm for the second half (sometimes earlier or later). It started on February 22^th.

Every point contains 6 measurements along with a Unix timestamp. Those measurements (and their accuracies) are :

• temperature in °C (± 0.5 °C),
• humidity in % (± 5 %),
• air pressure in hPa (± 0.12 hPa),
• wind speed in km/h (unknow accuracy),
• wind direction (see below for format) (unknown accuracy),
• battery voltage in V (± 0.1 V).

The data is available in two formats : JSON and CSV.

JSON

The JSON structure is the following :

• units : dictionary of measurements name and units,
• wind_direction_dic : dictionary of wind direction value and real direction,
• values : list of data point
  • [
    • timestamp : int,
    • temperature : float,
    • humidity : int,
    • pressure : float,
    • wind_speed : float,
    • wind_direction : int,
    • battery_voltage : float,
  • ]
  • ...

CSV

There are 2 CSV files :

• data_comma_period.csv : values are comma-separated, and periods (.) are used as decimal separator,
• data_semicolon_comma.csv : values are semicolon-separated, and commas (,) are used as decimal separator.

On the 29^th of August, the set contains 17473 data points.

Wind direction

The wind direction is an integer between 0 and 16 (inclusive), each one indicating a specific direction.

Integer	Direction
0	West
1	West-North-West
2	North-West
3	North-North-West
4	North
5	North-North-East
6	North-East
7	East-North-East
8	East
9	East-South-East
10	South-East
11	South-South-East
12	South
13	South-South-West
14	South-West
15	West-South-West
16	Invalid/Error
