Problem making feature with Netcdf files

IB3 — Fri, 18 Feb 2022 19:06:14 GMT

Hi community,

I need to create a few features from NetCDF files, but I am having issues with the Make feature from NetCDF tool..

Is there anyone that has experience with this type of files who could help me import my data?

I could explain the issues via Teams.

Thanks

Isabelle

@DanPatterson Yes, this tool.

1) First issue

I am downloading the NetCDF files from the Copernicus platform: https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-tourism-snow-indicators?tab=overview

This is my API request:

import cdsapi

c = cdsapi.Client()

c.retrieve(
    'sis-tourism-snow-indicators',
    {
        'time_aggregation': 'climatology',
        'variable': 'period_with_medium_height_of_natural_snow',
        'experiment': 'rcp8_5',
        'version': '1_0',
        'format': 'zip',
        'period': '2081-2100',
        'statistic': 'mean',
    },
    'download.zip')

When using the Make NetCDF feature layer tool, the lat and long are not displayed under the x,y variables.

What do I choose for row dimensions? Normally I put here the lat and long here.

---

I have also tried to upload the file with Make NetCDF raster layer, and I get the same problem. I can only choose between the 2 dimensions time and numbers of points (which is the altitude). The lat and long are not appearing, but are necessary for the good representation of the data.

2) Second issue

Data : https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-tourism-climate-suitability-indicators?tab=overview

import cdsapi

c = cdsapi.Client()

c.retrieve(
    'sis-tourism-climate-suitability-indicators',
    {
        'climate_index': 'climate_index_for_tourism',
        'variable': 'number_of_good_days',
        'product_type': 'multi_model_mean',
        'time_aggregation': 'monthly',
        'experiment': 'rcp8_5',
        'period': '2081_2100',
        'format': 'zip',
    },
    'download.zip')

I get a lot of 0 for the number of good days and it should not be the case...

I am new to this type of file, so I really appreciate your help and input. Thank you so much.

Hello Isabelle,

Thank you so much for your question in regarding the netCDF dataset you have.

The netCDF dataset you have is a DSG (see chapter 9 in CF convention) netCDF file that is not designed to be used in the Make NetCDF Feature Layer tool. Currently, we have developed a series of new netCDF tool that read in netCDF DSG dataset in particular. These tools will be available in Pro 3.0. I am a Product Engineer from Esri working with multidimensional dataset. Please let me know if you have any questions.

Best,

Yu Wang
