+
|
| 3 |
+
## Dataset Description
|
| 4 |
+
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:
|
| 5 |
+
- Sea Level Pressure (SLP)
|
| 6 |
+
- 2-meter Temperature (T2M)
|
| 7 |
+
|
| 8 |
+
The data covers a geographic region bounded by:
|
| 9 |
+
- Longitude: -15° to 0°
|
| 10 |
+
- Latitude: 42° to 58°
|
| 11 |
+
|
| 12 |
+
## Time Coverage
|
| 13 |
+
- Start Date: January 1, 2019
|
| 14 |
+
- End Date: December 31, 2021
|
| 15 |
+
- Temporal Resolution: Daily
|
| 16 |
+
|
| 17 |
+
## Data Format
|
| 18 |
+
- NetCDF4 files
|
| 19 |
+
- Each file contains a single day of data
|
| 20 |
+
- File naming convention: MERRA2_SLP_T2M_YYYYMMDD.nc
|
| 21 |
+
|
| 22 |
+
## Variables
|
| 23 |
+
- SLP: Sea Level Pressure
|
| 24 |
+
- T2M: 2-meter Temperature
|
| 25 |
+
|
| 26 |
+
## Geographic Coverage
|
| 27 |
+
The dataset covers Western Europe with:
|
| 28 |
+
- 25 longitude points (-15° to 0°)
|
| 29 |
+
- 33 latitude points (42° to 58°)
|
| 30 |
+
- Spatial resolution: ~0.625° x 0.5°
|
| 31 |
+
|
| 32 |
+
## Data Source
|
| 33 |
+
The data is derived from NASA's MERRA2 reanalysis dataset, processed to extract specific variables and geographic region of interest.
|
| 34 |
+
|
| 35 |
+
## Intended Use
|
| 36 |
+
This dataset is designed for weather analog search applications, allowing users to find historical weather patterns similar to current conditions in Western Europe.
