# Weather Tool
|
|
|
|
Tool for downloading historical and real-time data from 33 weather stations in Latvia. It aggregates and displays data for different time periods, cities, and weather parameters.
|
|
|
|
## Setup
|
|
Rename `.env-sample` to `.env` and fill in credentials
|
|
|
|
## Run
|
|
```
|
|
docker-compose up --build --no-cache --force-recreate
|
|
```
|
|
|
|
## Local synthetic weather data
|
|
|
|
The local database can be populated with deterministic hourly sample data for all 33 stations. The seed covers the previous 18 months through the current hour and can be run repeatedly without creating duplicates.
|
|
|
|
```sh
|
|
docker compose --profile tools run --rm seed
|
|
```
|
|
|
|
This workflow is intended only for development and UI testing. It uses the normal `weather` table and application APIs; it does not provide LVGMC forecast CSV or HARMONIE GRIB fixtures.
