 **BlackMarbleR** provides a simple and efficient way to retrieve and extract nighttime lights data from NASA's Black Marble project. [Black Marble](https://blackmarble.gsfc.nasa.gov) is a [NASA Earth Observatory](https://earthobservatory.nasa.gov) project that provides a product suite of daily, monthly and yearly global nighttime lights. This package automates the process of downloading all relevant tiles from the [NASA LAADS archive](https://ladsweb.modaps.eosdis.nasa.gov/archive/allData/5000/VNP46A3/) to cover a region of interest, converting the raw files (in HDF5 format), to georeferenced rasters, and mosaicing rasters together when needed.
