Hello NRI,
I am trying to calculate daily statistics from hourly ERA5 data using xarray. When calculating this for large datasets, it is very very slow. I have tried a number of optimisation techniques (like using Dask), but the problem still seems to persist. I want to do this for multiple 4D variables in a time efficient manner and would love some help. I know there has already been some discussion about this on this forum, so apologies for any overlap!
I was wondering if there is a collection of daily statistics for some general variables from ERA5 hosted somewhere on gadi that can be accessed? Is this a dataset the NRI can help support?
Thanks in advance!
Cheers,
Sramana

Hi @Sramana1. I’m not sure about whether there are pre-computed daily statistics available, but this topic is very similar to [Efficient daily resampling using xarray](https://forum.access-hive.org.au/t/efficient-daily-resampling-using-xarray/233) and there is a [solution therein](https://forum.access-hive.org.au/t/efficient-daily-resampling-using-xarray/233/6) that may help to speed up your resampling with xarray.

There are pre-computed daily variables available. I am looking for a place to make them available to the community.

Hi @Sramana1,
Getting back to you regarding this.
What variables do you need as a priority?
I gather from the hackathon notes that it would be
Tas
MSLP
Pr
Ta
Ua
Va
Wa
hus
Prw
Clt
rsut (sw)
rlut (lw)
rtnt
What do you think?
R

I currently have:
vas, uas, ua, tasmin, tasmax, tas, rsds, rlds, psl, pr, tdps, rsdt

Hi Romain,
Thanks so much for this! I would also like to access these variables. Where could I access them?

Hi Romain,
Apologies for the very late reply.
Your list is pretty comprehensive, I love it! Thank you. Just another question, would the 3D variables like ta, ua, va etc be available on multiple levels or just one?

I need to analyze ERA5 winds at 10 m and was wondering where on gadi I can find the data. I could only find data for 2023 in `/g/data/ik11/inputs/ERA5/input/IAF/10u`
Can any of you, @rbeucher or @rmholmes point me to the right directory?
Thanks,
Christina

Hi Christina - The data straight from ERA5 (3 hourly) is in `/g/data/rt52/era5/single-levels/reanalysis/` and [the link above](https://forum.access-hive.org.au/t/efficient-daily-resampling-using-xarray/233) might help to resample at a more useable frequency 🙂

The daily data are not publicly accessible for now. I am looking at how we can make this happen ASAP.

Hi - it would be wonderful to have tp and/or mtpr as well

hi @rbeucher - did anything ever come of this?! I am staring down the barrel of calculating daily precip (tp) but didn’t want to be reinventing that particular wheel if the daily data already exist somewhere.
thanks!

Hi @georgyfalster ,
Yes, we released some variables in August last year:
> [@Official release of the ACCESS-NRI Replicated Datasets for Climate Model Evaluation NCI Data collection](https://forum.access-hive.org.au/t/official-release-of-the-access-nri-replicated-datasets-for-climate-model-evaluation-nci-data-collection/1661/7):
>
> New Sub-collection: ESMValTool ERA5 Daily Datasets This is a prerelease dataset and consists of selected ERA5 variables presented at daily frequencies. The original hourly data from the “ERA5 hourly data on single levels” and “ERA5 hourly data on pressure levels” collections have been transformed into daily means using the ESMValTool (v2.10) Python package. Both the datasets and their associated metadata are provided in a format compatible with the ESMValTool Python package, which is supporte…
Data is available in ct11
For additional request, I suggest contacting @ClareCR
