NASA's ROSETTA-ORBITER 67P OSINAC 4 PRL-MTP006 RDR-REFLECT V1.0 dataset contains radiometric calibrated and geometric distortion corrected image data in reflectance units. The data was acquired by the OSIRIS Narrow Angle Camera on the Rosetta spacecraft during the PRELANDING mission phase from 2014-08-01 to 2014-09-02, targeting comet 67P/Churyumov-Gerasimenko. This version V1.0 is the first version of this dataset, corrected after an October 2018 PSA/PDS external peer review.
Radiometric calibrated and geometric distortion corrected image data acquired by the OSIRIS Narrow Angle Camera on the Rosetta spacecraft. The dataset covers observations of comet 67P/Churyumov-Gerasimenko from September 2 to September 26, 2016. This version 2.0 dataset was produced by NASA and includes updates to documentation, ancillary files, and image quality handling.
11 observation runs of approximately 8 hours each, plus calibration target data, were conducted by the International LOFAR Telescope during its cycle 2. The data are measurement sets containing cross-correlated data and metadata for the ELAIS-N1 sky field, divided into 371 frequency sub-bands per target centered at ~150 MHz. The dataset is hosted by the Institute for Astronomy, University of Edinburgh.
COMET Case Study 023 documents a strong extratropical cyclone from 8-11 November 1998. The case includes data on blizzard conditions in the Upper Midwest and severe thunderstorms over the Mississippi Valley. The dataset was compiled by SCIOPS and last updated on 11 November 1998.
1999 data focuses on Hurricane Floyd, a significant weather event causing 68 deaths and $2.5 billion in damages along the eastern U.S. coast. The dataset was compiled by SCIOPS and last updated on September 17, 1999. It provides a case study on the storm's heavy rainfall and flooding impacts.
Case 019 documents a severe convective event causing 48 deaths and several hundred injuries across Oklahoma and Kansas in May 1999. The dataset was compiled by the COMET program with contributions from UCAR, JOSS, NOAA, and CODIAC. It focuses on the tornado outbreak of May 3-4, 1999.
Case 018 documents two major convective weather events from 1998: a tornado impacting Spencer, South Dakota, and a long-lived derecho moving from Minnesota to New York. The dataset is part of a COMET case study series and was compiled by SCIOPS, with data sourced from UCAR/JOSS/NOAA/CODIAC. The last recorded update for this specific case is from June 1998.
Case 017 analyzes convective storm initiation and evolution in the southwest U.S. monsoon environment. The dataset was created by SCIOPS and published by UCAR/JOSS/NOAA/CODIAC. It focuses on severe weather events from August 1997.
COMET Case Study 016 analyzes the Moberly, Missouri tornado event from July 5, 1995. The dataset was compiled by SCIOPS and hosted by UCAR/JOSS/NOAA/CODIAC. It documents the atmospheric conditions leading to tornadic thunderstorm development.
COMET Case Study 014 documents a 1996 synoptic storm event in the Midwest, analyzed as a classical cyclone development example. The dataset was compiled by SCIOPS and hosted by UCAR/JOSS/NOAA/CODIAC. Data collection concluded on October 18, 1996.
Storm analysis data documents two major weather events from February 1998. A winter storm brought heavy rain to Southern California, while a separate system produced tornadoes in central Florida. The dataset was compiled by SCIOPS and last updated in February 1998.
1997 data documents a significant convective weather event across the southeastern United States, including the tornado in Jarrell, Texas. The dataset was compiled by SCIOPS and last updated in May 1997. It serves as a case study for analyzing severe storm patterns.
1996 data from a widespread aircraft icing event affecting the midwest, northeast, and northwest United States. The case study was compiled by SCIOPS and archived by UCAR/JOSS/NOAA/CODIAC. It was last updated in March 1996.
A major hydrologic event, the northern California flood from December 31, 1996, to January 3, 1997, produced impressive rainfall, river flooding, and levee breaches. The dataset is a case study compiled by SCIOPS for the COMET program, sourced from UCAR/JOSS/NOAA/CODIAC. The data was last updated on the final day of the event.
Meteorological data documents a major rainfall event over Chicago suburbs on 17 July 1996 and a severe thunderstorm with an F5 tornado in Eastern Wisconsin on 18 July 1996. The dataset was compiled by SCIOPS and archived by UCAR/JOSS/NOAA/CODIAC. The data was last updated on 19 July 1996.
COMET Case Study 004 documents a single, intense bow echo convective storm system that passed over Paducah, Kentucky on May 5, 1996. The dataset was compiled by the COMET program and archived through UCAR/JOSS/NOAA's CODIAC system. It captures the event's meteorological conditions and evolution for that specific date.
COMET Case Study 003 contains radar data collected during Hurricane Erin's impact on the southeastern United States in early August 1995. The dataset includes observations from Florida and Alabama radars. It was compiled by the UCAR/JOSS/NOAA/CODIAC project and last updated on August 4, 1995.
288 globular cluster candidates and 132 miscellaneous objects are cataloged in a 70 arcminute square field centered on the M31 Andromeda Galaxy. The catalog was compiled by NASA HEASARC.
The COSMOS2015 catalogue contains precise photometric red-shifts and stellar masses for more than half a million objects over the 2 deg^2 COSMOS field. It includes YJHKs images from the UltraVISTA-DR2 survey, Y-band from Subaru/Hyper-Suprime-Cam and infrared data from the SPLASH Spitzer Legacy program. This near-infrared selected catalogue is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
Gaia is a European Space Agency mission designed to chart a three-dimensional map of the Milky Way. The Gaia Catalogue DR1 provides unprecedented positional measurements for about one billion stars, together with radial velocity measurements for the brightest 150 million objects. This dataset is published by NASA and was last updated in March 2026.
