Results of sanitary controls in France can be found on data.gouv.fr however, only the running year is available… Thanks to @cquest@amicale.net we can access the archives since 2017.
First a global view of the dataset :
About 800 controls per week, except during the lock-down in 2020, and a slightly lower control pressure in 2021 and 2022.
Poor results (To be improved or To be corrected urgently) are stable at around 6 %, except a recent spike in 2023?
It seems that poor results increase during the year, from June to November.
This surprising periodic phenomenon is also visible by day :
So for the « when », it is : not in summer or autumn.
What about the « where »? It seems you also could be careful in some départements…
Not good in Guadeloupe, Guyane, Réunion and the southern lower Seine valley, west of Paris.
Can we see more in details ? Using a 30 km kernel smoothing :
It confirms some hot-spots west of Paris, in Alsace, in Indre, Cher, Alpes-Maritimes and between Gironde and Landes. You are safer in Paris and Bretagne…
It’s cherry blossom time… A nice dataset going back to the year 812 in Japan can be found here. It describes the phenological data for full flowering date of cherry tree (Prunus jamasakura) in Kyoto, showing springtime climate changes.
Today no cartography in R but in QGIS. However the satellite image processing has been made with the {sen2R} package.
We emulate infrared photography with a combination of the 8, 4 and 3 bands from the Sentinel-2 satellites, aimed at Termignon in the Vanoise National Park.
Glaciers (and clouds) in white, grasslands in light red, forest in dark red, sparsely vegetated areas in brown reds and rocks in grey.
