The US-network "FLUXNET-AMERIFLUX" has been updated until February 12, 2020. Since the provider supplied us with recently reprocessed data, we were able to update also previously available observations (2000-2013). For the two stations Tonzi Ranch and Vaira Ranch near Sacramento, California there are now almost 20 years of hourly soil moisture observations available.

We kindly thank Siyan Ma and Dennis D. Baldocchi for providing us the data.
