# Dataset Card for Weather Analog Search

## Dataset Description
This dataset contains processed MERRA2 (Modern-Era Retrospective analysis for Research and Applications, Version 2) weather data focused on Western Europe. It includes two key variables:
- Sea Level Pressure (SLP)
- 2-meter Temperature (T2M)

The data covers a geographic region bounded by:
- Longitude: -15° to 0° 
- Latitude: 42° to 58°

## Time Coverage
- Start Date: January 1, 2019
- End Date: December 31, 2021
- Temporal Resolution: Daily

## Data Format
- NetCDF4 files
- Each file contains a single day of data
- File naming convention: MERRA2_SLP_T2M_YYYYMMDD.nc

## Variables
- SLP: Sea Level Pressure
- T2M: 2-meter Temperature

## Geographic Coverage
The dataset covers Western Europe with:
- 25 longitude points (-15° to 0°)
- 33 latitude points (42° to 58°)
- Spatial resolution: ~0.625° x 0.5°

## Data Source
The data is derived from NASA's MERRA2 reanalysis dataset, processed to extract specific variables and geographic region of interest.

## Intended Use
This dataset is designed for weather analog search applications, allowing users to find historical weather patterns similar to current conditions in Western Europe.
