Global Data Availability: Data in Brief

Codes to accompany the Lewińska et al. (2004)[1] paper featuring the Global Data Global overview of cloud-, snow-, and shade-free Landsat (1982-2023) and Sentinel-2 (2015-2023) data featuring the dataset Lewińska et al., (2024)[2]. The prerequisite to executing the codes is the local copy of the Dataset featured in the publication.

• Figure_1.R code generates Figure 1 featured in the Lewińska et al. (2024a) paper;
• Figure_2.R code generating Figure 2 featured in the Lewińska et al. (2024a) paper;
• proportionOfDataPixels.js code deriving global statistics on proportion of acquired observations needed in the Figure_2.R script. To be executed in GEE
• Tab2Raster.R showcases the casting of the tabulated data from Lewińska et al. (2024b) as a georeferenced raster in the EPSG:4326 projection. A correctly casted resulting raster will have the following extend and projection definition:
