Elevation Change of the Southern Greenland Ice Sheet from 1978-88, Version 1

Southern Greenland ice sheet elevation change estimates are derived from SEASAT and GEOSAT radar altimetry data from 1978 to 1988. Data are confined to 61-72 deg N, 30-50 deg W, above 1700 m elevation. The addition of GEOSAT Geodetic Mission (GM) data results in twice as many crossover points and 50% greater coverage than previous studies. Coverage above 2000 m elevation is improved to 90%, and about 75% of the area between 1700 m and 2000 m is now covered. Data are in ASCII text format, available via FTP, and consist of elevation change rate (dH/dt, cm/year) and corresponding error estimates in 50 km grid cells.

Delta-X: AirSWOT L2 Geocoded Water Surface Elevation, MRD, LA, 2021, V3

This dataset contains Level 2 (L2) AirSWOT geocoded products, including estimated water surface elevation. The AirSWOT instrument is a Ka-band interferometer and for this study is flown on the King Air B200 platform. Data were collected during the DeltaX airborne campaign over the Atchafalaya and Terrebonne basins of the Mississippi River Delta, Louisiana, USA. Flights occurred during the Delta-X Spring 2021 deployment from 2021-03-26 to 2021-04-18 and the Delta-X Fall 2021 deployment from 2021-08-21 to 2021-09-12. AirSWOT is capable of producing high resolution (3.6 m) digital elevation models over land and water bodies using near-nadir wide-swath Ka-band radar interferometry to measure water-surface elevation and produce continuous gridded elevation data. The instrument includes six antennas that form multiple baseline pairs for along-track and across-track interferometry. AirSWOT elevation data are useful for calibrating elevation and slopes along the main channels, as well as tying observations to open ocean tidal conditions and is an airborne calibration and validation instrument for the Surface Water and Ocean Topography (SWOT) satellite. This Version 3 dataset provides updated data files due to an updated Calumet survey that changed the water level by 0.138 m. This resulted in all the AirSWOT water levels changing by that same amount. For these L2 products, only the estimated water surface elevation in respect to the WGS84 ellipsoid surface, and estimated height above the NAVD88 (GEOID12B) vertical datum files changed. Note that data acquired on September 1 and September 5, 2021 do not meet the expected MAE in-situ comparison and should be used with caution. This dataset contains cloud optimized GeoTIFF rasters in UTM map coordinates for each flight line. In addition, a text file provides basic metadata, including flight line ID, start and end UTC times of data acquisition, processor version number, and the date and time of different processing stages.

Delta-X: Matlab Model for Wax Lake Delta Land Accretion

This dataset provides the Matlab sediment transport and land accretion model at Wax Lake Delta (WLD), Atchafalaya Basin, in coastal Louisiana. The data include the Matlab scripts that solve the advection and Exner equations to simulate the suspended sediment transport and accretion at WLD. The model requires modeled flow information from a separate ANUGA hydrodynamic model as inputs. For this study, ANUGA modeled flow information from the Delta-X Spring and Fall 2021 campaigns were used as inputs. The ANUGA output files are converted to variables used by this Matlab model using pre-processing tools. The main code calculates suspended sediment fluxes and accretion rates of mud and sand as a function of space and time. The cumulative sediment accretion from each campaign was then used to estimate an annualized land accretion map using a weighted-average formula presented. The final product, the one-yr upscaled land accretion map, is archived as a separate dataset.

Delta-X: Bed and Suspended Sediment Grain Size, MRD, LA, USA, 2019-2021, V3

This dataset includes sediment concentration and grain size distribution measurements from suspended and bed sediment samples collected in the Atchafalaya River and Terrebonne Basins as part of the Delta-X Spring campaign between March 25 and April 2, 2021, and the Delta-X Fall campaign between August 17 and 22, 2021. In addition, ten samples were collected during a field campaign in October 2019. Samples were collected in the main channels and the interior of Mike Island in the Wax Lake Delta, Louisiana and at site CRMS0421 inside the Terrebonne Basin. Sediment samples were collected from a boat using a Van Dorn sampler (for suspended sediment samples) or a Ponar bed sampler (for bed samples). Suspended sediment samples were collected from a boat drifting at approximately the same velocity as the water flow. One sample was collected per drift. Bed samples were collected in a similar fashion. Data include measurements of sediment grain size distribution, total sediment concentration, water temperature, flow velocity, salinity, and depth. This Version 3 updates Version 2 to include data from more samples and reprocessed laser diffraction grain size distributions with optimized sediment optical properties. The data is provided in comma separated values (CSV) format.

Enhancing Knowledge of the Arabian Sea Marine environment through Science and Advanced Training (EKAMSAT)

Enhancing Knowledge of the Arabian Sea Marine environment through Science and Advanced Training (EKAMSAT) is a collaborative Indo-US field campaign funded by the Ministry of Earth Sciences, Govt. of India and the Office of Naval Research, USA, focused on the acquisition of contemporary oceanographic and atmospheric datasets deemed critical for improving the predictive skills of operational monsoon models. The atmospheric and oceanographic datasets acquired will be used primarily to examine how oceanographic conditions such as recent SST increases, enhanced stratification, formation of boundary layers, a recurring warm water pool and other changes in the Arabian Sea are influencing the onset, intensity and length of the Indian monsoon. The campaign commenced with a pilot study in June 2023 in preparation for subsequent full-fledged field campaigns in May-June of 2024-2025. This and the following cruises target atmospheric and oceanographic measurements supplemented with limited bio-optical and biogeochemical observations to advance understanding of the influence of seasonally evolving mixed layer on biological productivity and biogeochemical cycling in northern Arabian Sea. Microtops data available at https://aeronet.gsfc.nasa.gov/new_web/cruises_v3/Roger_Revelle_23_0.html .

Environmental Working Group Arctic Meteorology and Climate Atlas, Version 1

The Arctic Meteorology and Climate Atlas is part of the <a href="https://nsidc.org/data/ewg">NOAA@NSIDC Environmental Working Group (EWG) Atlases</a> data collection. The Arctic Meteorology and Climate Atlas was developed in the late 1990s by specialists from the Arctic and Antarctic Research Institute (AARI), St. Petersburg, Russia, the University of Washington, Seattle, and the National Snow and Ice Data Center, University of Colorado, Boulder. The Atlas contains three main sections: a history section, a Primer, and a data section. The history section summarizes Arctic exploration from both Russian and U.S. vantage points. It includes a condensed translation of an AARI publication detailing the Russian North Pole drifting station program, as well as a photo gallery from the North Pole stations. The Primer provides introductory information for newcomers to arctic meteorology. The data section contains gridded fields of meteorological parameters. These maps of air temperature, sea level pressure, precipitation, cloud cover, and snow and solar radiation from drifting and coastal stations can be browsed using an included viewer. Meteorological station data from Russian and other sources, newly released at the time the atlas was published, is included as well. In addition, the Atlas includes several English translations of Russian technical documents, and a glossary of meteorological terms in English and Russian. See the User Guide for a more complete listing of contents. The online User Guide includes an important Addendum and Errata section that is not included in the documentation that accompanies the Atlas download.
