- In this tutorial, I have demonstrated how to download ERA5 data and make times series from it using python code. You can download temperature, relative humidity, wind speed, cloud cover, rainfall, etc.

Hello.
To predict a phenomenon, I considered 7 variables as input and downloaded the ERA5 data for 41 years in NC format.
I want to use this data as input to LSTM model.
I need to convert this data into an Excel file.
With Python, I converted the ERA5 data into an Excel file, but the amount of data is too large, and I don’t know which data to consider to prepare the Excel file. Please advise. thanks.
Hi sr, Can you please do a video about how to extract data from LIS NASA lightning? I'd apreciate so much if you could help me understand how to extract a region data and how to plot it. Thx
Thank you for this video. It's really helpful. Please,how did you get get your locations (the ones in the excel)?
Thank you
The location is your choice and your point of interest. You can use a location within your study area.
It was an excellent presentation. I have one query regarding precipitation data. Since the nature of temperature and precipitation data are different, we can not do the same for precipitation data... I mean we can not claim the precipitation at given resolution of lat and lon will be same for the rainfall station having same lat log. Can you give your views in it. Even ERA 5 provides rainfall data in meter so if we wanto extract a rainfall data for a region (shape file) or for a station from the spatial data, what could be the approach and logic?
Hi Sir, I just view your tutorial..it works well for me. However, using your coding, why all stations (of course with different lat long) get the exact similar data? by looking at your plotting as well..i notice that all figures have similar output. Your respond is highly appreciated. Thanks
Hi, The stations I have used to demonstrate are located very close to each others and the resolutions of the data is such that the stations are almost falling within the same cell, that's why it looks like same time series but actually some of them are little different. Thank you for noticing it.
It is a very interesting tutorial. How can I convert GRIB data into CSV?. Here for example the River flow data can be downloaded only in.GRIB format. I have already downloaded the data in, GRIB format but am unable to convert it into CSV format. Please show me how? Thank you in advance.
Hi, thanks for the query. Yes, it’s possible to make csv from grib file. I demonstrate this in my training on data processing using python programming. For details send messages to +16825537054 on WhatsApp.
Thank You, Sir.
Sir I have a problem. I downloaded the gridded data fro sea surface temperature. Now how to apply shape file in this data to extract data only for Pacific Ocean sst. Can you help me out?
Thanks for the query. I offer training on Data processing using programming and ArcGIS, where I demonstrate how to download and process the data to the required format. For more details, send message to me on WhatsApp at +16825537054
Hi! I have a file of [latitude, longitude, time] and I want to extract hourly,monthy and historical precipitation of that region. Does the netcdf format automatically calculates the mean of that region wich is composed of numerous points of latitude and longitude when I calculate the average or mean for the variable i´m interested in , or do I have to do this for each point of latitude and longitude . Please! I´m dying over here help :c
Hi, thanks for your query. NO, it won't calculate the mean automatically. You need to calculate it using programming code. There are multiple ways to calculate and save the time series as multiple formats, including .csv, .xlsx, etc,. I provide training on data processing and deliver scripts to process any data.

Hello there, I have a clipped (of the exact study area that I am interested in) but a pretty big netCDF file (.nc file) of 1.64 gigabytes. Inside that file, there are three dimensions (lat., long., and day) and a data variable of 'monthly_precipitation' from 1901 to 2018. From that file, I need to extract the 'monthly_precipitation' data for only the years of 1980 to 2018 in .csv format. How can I do that ?
I'm desperately seeking your suggestions as I was madly looking for the hints of the solution of this particular problem for at least last ten days in youtube, github and literally everywhere.
I appreciate any type of responses from you in advance !
Hi thanks for your query. The problem you are facing is pretty simple and straight forward. If you have ideas about the data structure of .nc files, you can easily extract and make the time series; however, you probably want to make the time series for a particular location, Is that right?
hi, it's a good help to do like this video, it's helped me too, but L have a quiestion, how can I get a temperature date as a Celsius? because I get an hourly date like 275,45620 or something like it.
Thanks for the query, There might be some error in your data extraction and coding.
Hello, can you please explain how can I convert netcdf file data into pandas dataframe directly for all latitude and longitude?
Hi, I do that in my training session on scientific data processing using programming languages.
Can I adapt this script to WRF model variables? Do you know if you need to change the latitude/longitude interpolation routine?
Thanks!
Hi, yes you can follow this script, but you may need to change the variables and logic as well. I offer training on data processing using python where I demonstrate and write the customized scripts for the trainees. For more info, send message to +16825537054 on WhatsApp
Hi, where is possible to get the script? Thanks
Hi, what version of netcdf4 are you running for this?
Hi, it's NetCDF4 version, it does not matter, you can do the same to any version that's what I demonstrate in my training. For more details, send message to +16825537054 on WhatsApp.
please, provide the code sir
Hi the data are totaly free to download?
Yes, I also offer training on the data processing as well. For more info, send message to +16825537054 on WhatsApp. Thanks.
