Modelled VIIRS-DNB like night-time lights datasets (2004 to 2012)
The Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) night-time lights earth observation data (earlier provided by NOAA, now by Payne Institute) is at 1km spatial resolution and is available as yearly composites (1992-2013).
The Visible Infrared Imaging Radiometer Suite’s Day/Night Band (VIIRS-DNB) data is made available at 500m and as monthly composites (April 2012 - December 2019; as on February 20, 2020).
Two studies were done (Sahoo et al., 2019 and Sahoo et al., 2020) to generate annual composites of VIIRS-DNB data and inter-calibrate with DMSP-OLS, to generate time-series VIIRS-DNB-like night-time lights product. Futher a study was done (Jindal et al., 2022) to evaluate our products with other such published products. The publication Sahoo et al., 2020 was mentioned in NASA's training program on night light data (see answer to question 36).
In this repository the modelled VIIRS-DNB like NTL datasets (using multi-layer perceptron and random forest models) for 2004 to 2012 are made available for download by the researchers.
The study was done for the State of Uttar Pradesh, India. The files are georeferenced and in GeoTIFF format. Readers are referred to papers mentioned above for details of the process.
