TCW: Malaria Atlas Project Gap-Filled Tasseled Cap Wetness (Annual 1km)

AI-generated Key Takeaways

• This dataset, owned by The Malaria Atlas Project, provides gap-filled Tasseled Cap Wetness (TCW) data derived from MODIS imagery from 2001 to 2024.

• The TCW data was created by applying tasseled-cap equations to MODIS imagery and then gap-filled to address missing data.

• The dataset includes annual aggregations of the gap-filled data, with a pixel size of 5000 meters.

• The data is available under a CC-BY-NC-SA-4.0 license.

Description

This gap-filled Tasseled Cap Wetness (TCW) 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.
