Summary[edit]

Description
Français : Complément à la carte des couvertures nuageuses moyennes estivales recouvrant les régions de Paris et de Londres.

objet : couvertures nuageuses moyennes estivales recouvrant les régions de a) Paris et de d) Londres, selon l'heure de la journée.
a, d représentent respectivement la moyenne (cercles) et la médiane (carrés) + les étendues interquartiles (IQR, barres d'erreur) des différences de taux d'enuagement (nébulosité) pour la somme des pixels urbains et tous les pixels de végétation basse (vert clair) et tous les pixels de forêt (vert foncé ) pour a) Paris et d) Londres. Seuls les pixels HRV comportant 100% d'un type de couverture terrestre sont analysés.


...d'après une étude publiée en 2019 (Natalie E. Theeuwes, Janet F. Barlow, Adriaan J. Teuling, C. Sue B.
