This field campaign included a range of meteorological and oceanographic measurements from nearby NOAA, National Data Buoy Center (NDBC), and Academy weather stations.\r\n\r\nThe short-duration dataset includes measured $C_n^2$ along with atmospheric and oceanographic parameters from a co-located NOAA COOPS observation station between June 1\\textsuperscript{st}, 2021, and September 1\\textsuperscript{st}, 2021.\r\n\r\n## Details\r\n\r\n\r\nAdditional information\r\n * Frequency: 6 minute\r\n * Language: English\r\n\r\nCategories\r\n * Surface\r\n\r\nPlatforms\r\n * NOAA Coastal Observation Station 8575512\r\n\r\nInstruments\r\n * ScinTec BLS450\r\n * Davis Vantage Pro2\r\n\r\nTemporal coverage\r\n * Begin datetime: 2021-06-01 00:00:00\r\n * End datetime: 2021-09-01 00:00:00\r\n\r\nSpatial coverage\r\n * Maximum (North) Latitude: 38.98\r\n * Minimum (South) Latitude: 38.98\r\n * Minimum (West) Longitude: -76.48\r\n * Maximum (East) Longitude: -76.48\r\n\r\n\r\nPrimary contact information\r\n * author: Chris Jellen <cjellen@microsoft.com>","description_withheld":null,"homepage":"https://github.com/cdjellen/otbench","introduced_date":"2024-01-07","introduced_date_note":null,"introduced_by":{"paper":"/paper/effective-benchmarks-for-optical-turbulence","title":"Effective Benchmarks for Optical Turbulence Modeling","first_author":"Christopher Jellen","url":null},"license":{"name":"Creative Commons Attribution 4.0","url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"modalities":[{"name":"Time series","url":"/datasets/modality/time-series"}],"tasks":[{"name":"Time Series Forecasting","url":"/task/time-series-forecasting","datasets_with_task":"/datasets/task/time-series-forecasting"},{"name":"Time Series Regression","url":"/task/time-series-regression","datasets_with_task":"/datasets/task/time-series-regression"}],"languages":[{"name":"English","url":"/datasets/language/english"}],"variants":["USNA-Cn2 (short-duration)"],"data_loaders":[],"num_papers_in_archive":1,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/time-series-regression-on-usna-cn2-short","task":"Time Series Regression","dataset_variant":"USNA-Cn2 (short-duration)","rows":10,"metrics":["RMSE"],"first_row_in_archive_order":{"model":"Offshore Macro Meteorological","paper":"/paper/effective-benchmarks-for-optical-turbulence","metrics":{"RMSE":"0.178"},"code_links":[{"title":"cdjellen/otbench","url":"https://github.com/cdjellen/otbench"}]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"},{"leaderboard":"/sota/time-series-forecasting-on-usna-cn2-short","task":"Time Series Forecasting","dataset_variant":"USNA-Cn2 (short-duration)","rows":5,"metrics":["RMSE"],"first_row_in_archive_order":{"model":"GBRT","paper":"/paper/effective-benchmarks-for-optical-turbulence","metrics":{"RMSE":"0.160"},"code_links":[{"title":"cdjellen/otbench","url":"https://github.com/cdjellen/otbench"}]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/effective-benchmarks-for-optical-turbulence","title":"Effective Benchmarks for Optical Turbulence Modeling","date":"2024-01-07","rows_on_this_dataset":15,"code_links":1,"syntology":null}],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
