With the L4 all-weather product, we plan to extend the downscaling approach to other climatic regions. See Fig. 1 for an example of its application over Europe on July 1, 2014 (ascending passes). The version 2.0 is also provided (Fig. 2) to illustrate the differences between the two versions.
A quality report of the new product can be found here. This product, as well as its applicability in forestry applications (forest fire prevention and forest die-off predictability) will be presented at the 2nd SMOS Science Workshop in Madrid next week.
Note: the previous release of the L4 product over the Iberian Peninsula can still be accessed (version 2.0)
