Nearest INMET Weather Stations for Brazilian Municipalities
Source:R/mun_stations.R
mun_stations.RdA dataset containing the five nearest INMET weather stations for each Brazilian municipality based on the distance between the municipality centroid and the station location.
Format
A tibble with 27,850 rows and 4 variables:
- state_muni
Brazilian state abbreviation.
- code_ibge7
Seven-digit IBGE municipality code.
- code_wmo
World Meteorological Organization (WMO) identifier of the INMET weather station.
- distance
Distance between the municipality centroid and the station, in kilometers.
- station_order
Rank of the station by proximity, where 1 indicates the nearest station.
Source
Distances were computed from municipality centroid coordinates and INMET station coordinates using the Haversine formula.
Details
Distances were calculated using the Haversine formula. Each municipality is associated with its five closest INMET stations, ordered by increasing distance.
The dataset was generated using the `nearest_stations()` function from the climateBR package, matching municipality centroids to the five closest INMET weather stations available in the package's `inmet_stations` dataset.
This dataset is based on the most recent version of the INMET station network available in the package. It is intended for analyses using recent observations. Because the INMET network changes over time (stations may be added or removed), this dataset should not be used to match historical data from earlier years. For historical analyses, users should create a year-specific municipality-to-station mapping using the corresponding historical INMET station
