I am accessing 3 hourly GLDAS time series (GLDAS_NOAH025_3H v2.1) for a single lat/long point with a curl request for a csv file. At the moment I am also only requesting a single variable, though I will be requesting more. My authentication details are correct. When I do a shorter time request, I get the desired CSV.

For example, the following command successfully downloads a small CSV file with 5 months of 3-hourly snowfall records for the queried site:

curl -n -L -O -b ~/.urs_cookies "https://hydro1.gesdisc.eosdis.nasa.gov/thredds/ncss/grid/GLDAS_aggregation/GLDAS_NOAH025_3H.2.1/GLDAS_NOAH025_3H.2.1_Aggregation_2000.ncml?var=Snowf_tavg&latitude=45.2929&longitude=-75.767&time_start=2000-01-01T03:00:00Z&time_end=2000-05-01T21:00:00Z&&&accept=csv_file"

However, if I expand the request to all of the year 2000, I end up with an internal server error. Looking more closely, the common thread is that the data download component of the request always cuts out after 10 minutes:

% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 761 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0
100 587 0 587 0 0 886 0 --:--:-- --:--:-- --:--:-- 886
0 477 0 0 0 0 0 0 --:--:-- 0:00:01 --:--:-- 0
100 527 0 527 0 0 0 0 --:--:-- 0:10:01 --:--:-- 145

In contrast, requests that stay under that 10:00 download time always succeed.

We have limitations on our servers to minimize impacts when lots of traffic is coming through. We suggest you look into using our Data Rods service for GLDAS_NOAH025_3H v2.1. This may get you a longer time period of the data you need. Data Rods can supply a time series of nearly 200,000 values without running into problems.

That is exactly what I need. Thank you!
