Precipitation data in ERA5 is a forecast field: twice a day (at 06:00 and 18:00) forecast data is calculated for the next 18 hours.

The retrieval is slow, as the data has to be fetched from MARS at ECMWF, but the retrieval is only run if necessary - if that month’s data has been previously fetched and is already on local disc, the fetch command will detect this and return instantly. ERA5 data is available from 1979 to three months from real-time. Spatial resolution: The ERA5 data are provided for half-degree grid boxes. Earth Engine is free to use for research, education, and nonprofit use. Reanalysis combines model data with observations from across the world into will retrieve precipitation rate data for the selected date.

ERA5 data has a time resolution of one hour, whereas the earlier ERA Interim and ERA40 produced data of four values a day.

the ERA-Interim reanalysis. ERA5 data are updated regularly with new products that you can download. I wanted data at a lower resolution, and only for 20-90N. So at 21:00, for example, there are 2 sets of precipitation available: a 3-hour forecast starting at 18 that day, and a 15-hour forecast starting at 06:00, and there is a discontinuity between the two fields. Reanalysis combines model data with observations from across the world into a globally complete and consistent dataset. the Licensee shall inform the recipients of the source by using the following or any similar notice: "Generated using The great thing about using a script, instead of downloading directly from the CDS, is that it gives you more control.

ERA5 DAILY provides aggregated values for each day for seven ERA5 climate
This function will always load the shortest lead-time forecast available unless fc_init is set (to 6 or 18) in which case it will load the forecast starting at the hour specified.

I was able to specify this in my retrieval script: And this quickly retrieved the required data!

The ERA5 CDS page for ERA5 monthly averaged data on … air temperature at 2m has been calculated based on the hourly 2m air For analysis fields (everything except prate), this issue does not arise and fc_init is ignored. ERA 5 comes in two streams: the ‘oper’ stream is a single member analysis at highest resolution, and the ‘enda’ stream is a 10-member ensemble at lower resolution - both are supported.

Reanalysis combines model data with observations from across the world into a globally complete and consistent dataset. Load requested data from disc, interpolating if necessary. Get all data for one variable, for one month, from ECMWF’s archive. The Climate Corporation has distributed the ECMWF API Python Client on pypi. Data must be available in directory $SCRATCH/ERA5, previously retrieved by fetch().

Additionally at the CDS and/or ECMWF, monthly means of different hours of the day separately are available, as well as the total monthly mean of all data of a certain parameter. There are climate datasets that range from 1950 to present, or 1981 to present depending on the variable of interest.

ERA5 data are available in the Climate Data Store on regular latitude-longitude grids at 0.25 o x 0.25 o resolution, with atmospheric parameters on 37 pressure levels.
