Error accessing E-OBS data

[jesusff]

Message transferred from email inquiry from M. Rodrigues:

I've encountered another problem when running:

di <- dataInventory(eobsNcML)

> eobsNcML
[1] "http://opendap.knmi.nl/knmi/thredds/dodsC/e-obs_0.25regular/rr_0.25deg_reg_v17.0.nc"

I get the following error:

[2024-04-11 00:13:13.802706] Doing inventory ...
Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl,  : 
  java.lang.NullPointerException: Cannot invoke "org.apache.http.client.methods.CloseableHttpResponse.close()" because "closeableHttpResponse" is null

I have followed the instructions from the Supplement of "Iberia01: a new gridded dataset of daily precipitation and temperatures over Iberia".

My system and R info are:

R version 4.3.2 (2023-10-31)
Platform: aarch64-apple-darwin20 (64-bit)
Running under: macOS Ventura 13.2.1

The climate4R package versions are:

other attached packages:

[1] loadeR_1.8.1       convertR_0.2.1     transformeR_2.2.2  visualizeR_1.6.4  
[5] RColorBrewer_1.1-3 rJava_1.0-11  

Has anyone encountered this problem before and how to solve it?

Thank you for your time.

Kind regards,

Miguel

It seems that the KNMI server is down at the moment: http://opendap.knmi.nl

You can access E-OBS data as a climate4R "local" dataset (see #65 )

After trying to open observation:

#9 E-OBS_v17_0.25regular observation https://data.meteo.unican.es/thredds/dodsC/eobs/e-obs_v17_0.25regular.ncml

eobsNcML_repo <- "https://data.meteo.unican.es/thredds/dodsC/eobs/e-obs_v17_0.25regular.ncml"

I get the following error:

[2024-04-11 10:22:55.735335] Doing inventory ...
[2024-04-11 10:22:56.521254] Opening dataset...

@msirodrigues Could you try again? This is working for me. Also, this is a protected dataset, remember to call loginUDG before accesing the dataset.

[msirodrigues]

@zequihg50 the credentials are set with success, it is only when I try to open the dataset that the error occurs. Do I need to join a specific group in https://data.meteo.unican.es/udg-tap/home to have access to the dataset? Thank you.

[zequihg50]

@msirodrigues Yes, you should have access now to the dataset.

@zequihg50 thank you, just managed to access it.
