Hello Mike,

I tried one example from here but got this error message. Do you know what went wrong? Thank you very much for your help!

pst = readNWMdata(comid = 101, 
                  startDate = "2010-01-01", 
                  endDate = "2010-01-31", 
                  tz = "US/Pacific")

syntax error, unexpected WORD_WORD, expecting SCAN_ATTR or SCAN_DATASET or SCAN_ERROR

data for climate and land use. Datasets can be subsetted or summarized before download using several algorithms, and these algorithms can also be applied to other datasets hosted elsewhere.</p><p>The system has been hosted via <code>cida.usgs.gov</code> since its original release in 2011. See this report for more information on GDP: Blodgett, David L., Nathaniel L. Booth, Thomas C. Kunicki, Jordan I. Walker, and Roland J. Viger. Description and testing of the Geo Data Portal: Data integration framework and Web processing services for environmental science collaboration. <a href=https://pubs.usgs.gov/of/2011/1157/>No. 2011-1157. US Geological Survey, 2011.</a></p><p><em>As of April 2024, most of the datasets the GDP supports are no longer accessible. See the THREDDS Data Server section below for more information.</em></p><p>All components of the GDP were migrated to a new hosting environment in 2022. Due to a lack of resources to maintain the software, the GDP will be retired in Summer 2024. It will be replaced by analysis ready cloud optimized direct data access via methods <a href=https://water.usgs.gov/catalog/usecases/71a9ec77-a83f-4f14-92eb-d7c3266078ce/>(such as those described here)</a> and an in development processing service based on the <a href=https://code.usgs.gov/wma/nhgf/toolsteam/gdptools>gdptools</a> python package.</p><h1 id=thredds-data-server>THREDDS Data Server</h1><p>The GDP THREDDS Data Server (<a href=https://cida.usgs.gov/thredds/>https://cida.usgs.gov/thredds/</a>) was retired due to a lack of resources to remedy a security vulnerability in April 2024. We apologize for the abrupt retirement of the system. Research and development aiming to migrate THREDDS to a cloud-based infrastructure in 2022-2023 led to the conclusion that migration away from the THREDDS data server toward cloud optimized analysis ready data access methods was necessary. This work is nearing completion and all data that were available are or will soon be available in zarr format via a freely available object store. Information regarding how to <a href=https://water.usgs.gov/catalog/usecases/8df9f64f-0f38-4849-9c6f-3d931fd2b2ba/>access the object store can be found here</a>. A Spatio Temporal Asset Catalog will be released soon to aid discovery of these datasets and OPeNDAP access (as was provided by THREDDS) to the datasets should be available again soon.</p><p>To keep up with development on STAC, see <a href=https://code.usgs.gov/wma/nhgf/stac>this repository</a>.</p><p>In the coming months, new APIs and processing capabilities will become available via api.water.usgs.gov to replace the Geo Data Portal. Stay tuned for more user friendly APIs, more cloud-ready data access options, and a generally refined ecosystem of data, services and tools. No release date is set, but please check back here for more information or reach out to <a href=mailto:dblodgett@usgs.gov>dblodgett@usgs.gov</a> with questions.</p><div class="grid-row border-y

Hi @tungttnguyen! Thanks for reaching out. Unfortunately the USGS CIDA server was hacked and is not expected to be restored :/ That puts us in a bit of a struggle until the OSN system is back up. I can help get you access to 1.2 and 2.0 but we lost 2.1 temporarily. Are you interested?

Yes please. Thanks Mike!

csimeone-usgs · 2024-04-30T20:16:10Z

@mikejohnson51, if its not too much trouble, would it be possible for me to get access to versions 1.2 and 2.0 as well? Thank for your help!

mikejohnson51 · 2024-04-30T21:08:48Z

Certainly! I will get this set this week and update you both when its done.

lindsayplatt · 2024-05-20T17:58:26Z

Hello! I am also looking for this fix. I was just trying with version = 2.0 and version = 1.2 but both failed. I am using nwmTools v0.0.4.

library(nwmTools)
nwm_output <- readNWMdata(comid = 6078267, 
                          startDate = "1993-01-01",
                          endDate = "2017-12-31",
                          version = 1.2)

Datasets can be subsetted or summarized before download using several algorithms, and these algorithms can also be applied to other datasets hosted elsewhere.</p><p>The system has been hosted via <code>cida.usgs.gov</code> since its original release in 2011. See this report for more information on GDP: Blodgett, David L., Nathaniel L. Booth, Thomas C. Kunicki, Jordan I. Walker, and Roland J. Viger. Description and testing of the Geo Data Portal: Data integration framework and Web processing services for environmental science collaboration. <a href=https://pubs.usgs.gov/of/2011/1157/>No. 2011-1157. US Geological Survey, 2011.</a></p><p><em>As of April 2024, most of the datasets the GDP supports are no longer accessible. See the THREDDS Data Server section below for more information.</em></p><p>All components of the GDP were migrated to a new hosting environment in 2022. Due to a lack of resources to maintain the software, the GDP will be retired in Summer 2024. It will be replaced by analysis ready cloud optimized direct data access via methods <a href=https://water.usgs.gov/catalog/usecases/71a9ec77-a83f-4f14-92eb-d7c3266078ce/>(such as those described here)</a> and an in development processing service based on the <a href=https://code.usgs.gov/wma/nhgf/toolsteam/gdptools>gdptools</a> python package.</p><h1 id=thredds-data-server>THREDDS Data Server</h1><p>The GDP THREDDS Data Server (<a href=https://cida.usgs.gov/thredds/>https://cida.usgs.gov/thredds/</a>) was retired due to a lack of resources to remedy a security vulnerability in April 2024. We apologize for the abrupt retirement of the system. Research and development aiming to migrate THREDDS to a cloud-based infrastructure in 2022-2023 led to the conclusion that migration away from the THREDDS data server toward cloud optimized analysis ready data access methods was necessary. This work is nearing completion and all data that were available are or will soon be available in zarr format via a freely available object store. Information regarding how to <a href=https://water.usgs.gov/catalog/usecases/8df9f64f-0f38-4849-9c6f-3d931fd2b2ba/>access the object store can be found here</a>. A Spatio Temporal Asset Catalog will be released soon to aid discovery of these datasets and OPeNDAP access (as was provided by THREDDS) to the datasets should be available again soon.</p><p>To keep up with development on STAC, see <a href=https://code.usgs.gov/wma/nhgf/stac>this repository</a>.</p><p>In the coming months, new APIs and processing capabilities will become available via api.water.usgs.gov to replace the Geo Data Portal. Stay tuned for more user friendly APIs, more cloud-ready data access options, and a generally refined ecosystem of data, services and tools.
