TCB: Malaria Atlas Project Gap-Filled Tasseled Cap Brightness (Annual 1km)

  • This dataset provides gap-filled Tasseled Cap Brightness (TCB) data derived from MODIS imagery, processed to eliminate missing data and clipped to valid value ranges.

  • The original 8-daily data are aggregated into monthly and annual products with a pixel size of 5000 meters.

  • The dataset covers the period from 2001-02-01 to 2024-01-01 and is updated annually.

  • This dataset is available under the CC-BY-NC-SA-4.0 license.

  • The data is provided by The Malaria Atlas Project.

Description

This gap-filled Tasseled Cap Brightness (TCB) dataset was created by applying the tasseled-cap equations defined in Lobser and Cohen (2007) to MODIS BRDF-corrected imagery (MCD43B4). The resulting data were gap-filled using the approach outlined in Weiss et al. (2014) to eliminate missing data caused by factors such as cloud cover. After gap-filling the data was clipped to thresholds of [-1, 2] to ensure valid values.

The gap-filled 8-daily ~1km outputs are then aggregated temporally to produce monthly and annual products.
