# 🌍 NASA POWER Hourly Data Downloader Ver.2
This project automates the downloading and merging of hourly climate data from [NASA POWER API](https://power.larc.nasa.gov/).
## 🚀 Features
👉 Downloads hourly weather data (2014–2024)
👉 Splits requests into smaller chunks (1 year per request)
👉 Cleans and removes unnecessary headers from downloaded CSV files
👉 Automatically merges data into a single CSV file
👉 Saves cleaned and merged data in organized directories
👉 Handles API errors with a retry mechanism
