Download observation data

Get Observation Data CLI

This script is for downloading observation data from Dataex server. Users can get the desired observation data in the selected format for a specific observation parameter and station.

Usage

$ dataex_get_obs_data.py --start_date <YYYY-MM-DD> --end_date <YYYY-MM-DD> -- station_id <int> --parameter_id <int> --output_type <str> --output <str>

Tip

Option names too long, you can always use their short forms. Check using --help

Options

start_date   : DateTime
               Date in YYYY-MM-DD format

end_date     : DateTime
               Date in YYYY-MM-DD format

station_id   : int
               station id

parameter_id : int 
               parameter id   

output_format  : str
               json, table or csv       

output       : str
               output filename

Output type and output options are not required. The default output type is table.

Info

Users can get station and parameter id numbers using dataex_obs_station_list.py and dataex_obs_parameter_list.py respectively.

Example

dataex_get_obs_data.py --start_date 1994-11-01 --end_date 1994-12-10 -si 53 -pi 7 --output_format csv --output ./obs_data.csv

It goes without saying that the start_date must be a date that is earlier than the end_date. The time period should be within 180 days.

Info

In case the time period is beyond 180 days, the server just returns a truncated observation dataset of 180 days instead.

dataex_get_obs_data.py --start_date 1994-11-01 --end_date 1994-12-10 -si 53 -pi 7

Here, observation data will be displayed in tabular form in the terminal.
