Due to strong #jetstream which, since end of November, dumped one moist Atlantic Low after the other over middle and Northern Germany, her Northern rivers were overflowing since before Christmas. Newsreporting and live ticker never said how big the actual affected area is. But it felt like a third of the country at least – just from the persistent presence in my news feed and in my mind.
Today, I pondered how I could get figures for hectare if journalists don't report them... first, I thought of #NASA GRACE drought monitoring which could maybe be used in reverse or whatever. But then I found something better: Germany had activated @CopernicusEU to monitor several rivers in their program #RapidMapping. Since the activation, #Sentinel 🛰️ takes a photo every day and the software guesstimates flooded hectare, flooded roads, rails and affected number of people.
You can find your own country's past or active Copernicus activations here https://rapidmapping.emergency.copernicus.eu/
Germany's current one for Lower Saxony is here https://rapidmapping.emergency.copernicus.eu/EMSR712/download
The hectares flooded, 46365, appear to be 0.12% of the country's area 357600 km2
Okay. Not a third of the country, then 😁
