The user can define the product which should be turned into a TIFF and also mosaic from a list of file-paths. If no product is defined, the user will be prompted to choose from a list of products. Optionally the spatial resolution of the output imagery, as well as an area of interest to which the imagery will be masked, can be defined. Furthermore, the user can choose whether the pixel values should be either in mol per m² or molecules per cm².
Below an examplary R script:
