Water, Energy, and Carbon with Artificial Neural Networks (WECANN): A statistically-based estimate of global surface turbulent fluxes using solar-induced fluorescence.
WECANN is a monthly product, at 0.5-degree resolution, starting in 2007. It typically outperforms other global estimates.
Our machine learning retrieval CU-NN-AP (Columbia U., Neural Network, Active Passive) of soil moisture based on active and passive microwave measurements (ASCAT and AMSR) is available here:

Isohydricity Index Based on Vegetation Optical Depth
This dataset represents microwave vegetation optical depth-based calculations of ecosystem scale isohydricity. It is kindly hosted by my colleague Alexandra Konings
Reconstructed Solar Induced Fluorescence (RSIF)
A new MODIS-based product of vegetation productivity based on machine learning, with GOME-2 Solar Induced Fluorescence as a training dataset. The data shows very good interannual variability compared to FLUXNET GPP.
The data is available here
