This project contains software for calculating the Australian Combined Drought Indicator (CDI) for NACP's Drought Monitor product. The Australian CDI provides a view of general drought conditions across Australia.
When using download.py to download the latest data, it will always redownload the latest year's (currently 2019) file. This works well for datasets where the data is split into yearly files (min_temp, max_temp, monthly_rainfall, etc.)
NDVI is downloaded from BoM's website in monthly files, so redownloading the entire year is a waste.
Suggested fix: Only download the file for the current year and month for NDVI.
