The Netherlands has broken the country's all time driest start of the summer since we started looking at droughts with satellites. We have not seen these levels in June on such a widespread scale in 40 years of satellite soil moisture observations.
In this case VanderSat looked at root zone soil moisture levels. The level where most crops get their water and nutrients.
VanderSat does not look at rainfall, but looks at the direct source: soil moisture, which is influenced only partly by rainfall. Some spots in the Netherlands needs hundreds of liters of water per square meter to get back to normal levels.
