The Antarctic Laboratory for Cosmic Rays (LARC) records the nucleonic component of galactic cosmic rays using a 6-NM-64 detector in the South Shetlands. Data collection began in January 1991, with primary research goals including the identification of Ground Level Enhancements (GLEs). The dataset was last updated on November 2, 2003.
Six-frequency passive-microwave radiometer data provides vertically and horizontally polarized brightness temperature measurements at 6.925, 10.65, 18.7, 23.8, 36.5 and 89.0 GHz. The instrument, with a 1.6-meter reflector, scans the Earth at a constant 55-degree incidence angle, offering spatial resolutions from 5.4 km to 56 km. Data was collected by the AMSR-E instrument on NASA's Aqua satellite, managed by the AMD_KOPRI organization, with observations beginning in 2002.
Twenty-two case studies from the Cooperative Program for Operational Meteorology, Education and Training (COMET) project, archived for educational use. Each case study includes a description, dataset information, and sample imagery related to specific weather events. The archive was created by UCAR/JOSS and made available via the CODIAC system, with data last updated in January 2002.
Tropical Storm Allison produced a record 37 inches of rain at the Port of Houston in June 2001, causing over $4.88 billion in damage in Harris County alone. The case study documents the storm's path, rainfall totals, and impacts across Texas, Louisiana, and the Eastern United States. SCIOPS compiled this analysis of the event, with data last updated on June 19, 2001.
Gravity gradient seismic noise characterization was conducted at the LIGO Livingston Observatory in Louisiana. Researchers from SCIOPS performed measurements using Guralp sensors, focusing on frequencies between 1-30 Hz. The dataset was last updated in June 2001.
Thirty piston cores, ranging from 15 to 23 meters in length, were recovered at various latitudes during the RV Polarstern ANT/XVIII/5 campaign. The expedition, conducted by SCIOPS, also collected centimeter-sized meteoritic fragments near 57°S/92°W and water column samples for coccolithophore analysis. Data collection concluded in April 2001.
COMET Case Study 036 documents a major snowstorm that hit Seattle on February 16, 2001. The event involved an arctic front from Canada interacting with Pacific air, producing snow accumulations from four to eight inches in lowlands and up to a foot in hills. The case study was published by UCAR/JOSS/NOAA/CODIAC and last updated on February 17, 2001.
2000-2001 data from an Imaging Riometer deployed during the 17th Chinese National Antarctic Research Expedition (CHINARE). The instrument measures cosmic noise absorption in the ionosphere's D-region using an 8x8 antenna array, providing spatial monitoring over a 300x300 km area. Data was recorded on MO disks and shared between the Polar Research Institute of China and Japan's National Institute of Polar Research.
COMET Case Study 032 documents a severe lake-effect snowstorm that struck Buffalo, New York, on 20 November 2000. The event delivered two feet of snow in a short period, with intense snowfall and frequent lightning occurring during the afternoon. The case study was contributed by SCIOPS to the UCAR/JOSS/NOAA/CODIAC repository and last updated on 21 November 2000.
Over 9 inches of rain fell in 8 hours during a terrain-locked convection event over Sparta, New Jersey, on August 12, 2000. This case study documents the flooding rains that closed roads, washed out bridges, and caused mudslides. The data was compiled by SCIOPS and published by UCAR/JOSS/NOAA/CODIAC.
21 May 2000 was the date of isolated severe thunderstorms in northwest Missouri, producing hail, wind gusts, and an F1 tornado. This case study from UCAR/JOSS/NOAA/CODIAC serves as a teaching resource for identifying subtle triggers of severe weather. The data was published by SCIOPS and last updated on 22 May 2000.
COMET Case Study 031 documents a null severe weather event on April 19, 2000, where a strong atmospheric cap prevented convection despite favorable conditions. The case study, created by SCIOPS, analyzes model forecasts and observational data for Kansas, Oklahoma, and north central Texas. It serves as an educational example of forecast challenges in meteorology.
COMET Case Study 028 documents a significant tornado outbreak in Texas and Louisiana on March 28, 2000. The dataset includes details on tornado tracks, Fujita scale ratings, damage estimates, and WSR-88D radar indications. It was compiled by SCIOPS and published by UCAR/JOSS/NOAA/CODIAC shortly after the event.
COMET Case Study 030 documents a null weather event where forecasts predicted over a foot of snowfall for Eastern Colorado's Front Range on March 20, 2000, but only 3 to 5 inches were reported. This case is the first in a series of null-event studies compiled by SCIOPS. The data was last updated on March 21, 2000.
Case 024 documents the formation and rapid intensification of a cyclone off the southeastern U.S. coastline in January 2000. The storm moved north, affecting the entire eastern seaboard and causing heavy snow from the Carolinas to New England, with at least 5 deaths reported. The data was compiled by SCIOPS and hosted by UCAR/JOSS/NOAA/CODIAC.
Antarctic and transit flight data contains direct measurements of cosmic ray neutron flux, temperature, pressure, and time from a portable detector. Measurements were collected at sites including Scott Base, Mt. Erebus, and during flights between 1997 and 2000. The dataset was produced by SCIOPS in conjunction with studies on cosmic ray produced nuclides in rocks.
Tree-ring data from New Mexico reconstructs fire history over a 580-year period from 530 to -50 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was last updated in the year 2000.
