Data sets

The global long-term microwave vegetation optical depth climate archive VODCA (1.0) L. Moesinger, W. Dorigo, R. De Jeu, R. Van der Schalie, T. Scanlon, I. Teubner, and M. Forkel

ESA Soil Moisture Climate Change Initiative (Soil_Moisture_cci): COMBINED Product, Version 04.7 ( W. Dorigo, W. Preimesberger, A. Pasik, L. Moesinger, R. Van der Schalie, S. Hahn, T. Scanlon, W. Wagner, A. Gruber, R. Kidd, C. Paulik, C. Reimer, and R. De Jeu

Short summary
For the first time, microwave vegetation optical depth data are assimilated in a land surface model in order to analyze leaf area index and root zone soil moisture. The advantage of microwave products is the higher observation frequency. A large variety of independent datasets are used to verify the added value of the assimilation. It is shown that the assimilation is able to improve the representation of soil moisture, vegetation conditions, and terrestrial water and carbon fluxes.
