I am using temperature information from ERA5 reanalysis hourly data on a single level, and I am confused about time reference.
If I download global temperature data for a specific day and time (for example, 2000-08-08 07:00) is this UTC or is it adjusted to the local time of each point of the grid? In other words, will I be looking for 07:00 in the US and also for 07:00 in Germany? Or they are referred to UTC, and in the US I will be looking for nighttime temperature while in Germany it will already be morning?
