[Q] GES DISC OCO-2 OPeNDAP Service?

[hyoklee]

Hi,

I'm trying to subset data from OCO2_L2_Lite_FP.11.3r using OPeNDAP service [1]
but I keep getting the following error message:

Concurrent Connection Limit Reached

The server is temporarily unable to service your request because your IP address has reached the limit of concurrent connections. If you feel you have received this message in error, please contact GES DISC user services .

I haven't used the OCO-2 OPeNDAP service.
Thus, I'm wondering if the error message is really valid or not.
Does anyone have the same problem with [1]?

Dear User,

We do see that the exact URL you provided to us results in a '400 Bad Request' error on our end. However, we recommend you try your request again with the following revised URL, which includes HTML encoding in the URL string:
http://oco2.gesdisc.eosdis.nasa.gov/opendap/OCO2_L2_Lite_FP.11.3r/2026/oco2_LtCO2_260101_B11300Ar_260529211516s.nc4.dap.nc4?dap4.ce=/L1b_latitude%5B0:1:123534%5D%5B0:1:0%5D;/L1b_longitude%5B0:1:123534%5D%5B0:1:0%5D;/L1b_land_fraction%5B0:1:123534%5D%5B0:1:0%5D

You can also try downloading the data using the following URL, which doesn't include encoding and omits the dimension brackets. However, note that it retains the data's original swath dimensions (123534x8), versus the subset of 1 column (123534x1) like in the original request you attempted:
https://oco2.gesdisc.eosdis.nasa.gov/opendap/OCO2_L2_Lite_FP.11.3r/2026/oco2_LtCO2_260101_B11300Ar_260529211516s.nc4.dap.nc4?dap4.ce=L1b_latitude;L1b_longitude;L1b_land_fraction

Please give these URLs a try, and let us know if you continue to encounter any errors. Thank you.
