A new high spatial density temperature dataset in the Grenoble alpine valley (France) for urban heat island investigation and climate services dedicated to municipalities purposes

Data came from urban heat island studies led by Xavier Foissard for the city of Echirolles and the city of Grenoble. A total of 62 measurement points has been installed in the various neighborhoods on 3-meter-high streetlights, starting in summer 2019. The temperature sensors were equipped with a Tinytag Talk 2 data logger (Gemini Data Loggers) protected by a solar RS3 radiation shields (ONSET). The preliminary classification of the various neighborhood typologies according to "Local Climate Zone" guided the choice of location for the temperature sensors. These urban observations respond to a dual challenge: firstly, to observe temperature located in complex topographical situations with valleys, and secondly, to observe the urban climate in neighborhoods where social considerations are important. The municipalities of Echirolles and Grenoble were involved in the investigation.
Following these investigations, the work became part of the CASSANDRE research program funded by ADEME (French Agency for Ecological Transition). These data were described in detail in a data paper.
