This paper evaluates the performance of a new type of 2 V traveling cryocooled Programmable Josephson Voltage Standard for performing on-site verification of quantum voltage standards. Direct comparison with a 10 V system showed agreement of 8 parts in 10^11 at 2 V. This result shows that, despite the lower voltage, the direct Josephson-to-Josephson system comparison method provides a two orders-of-magnitude improvement over traveling Zener standards for verifying Josephson voltage standards.

This dataset contains two-port S-parameter measurements (S2P format) acquired in a typical mode-stirred reverberation chamber. The measurements support training of artificial neural networks to infer optimal mechanical stirrer and turntable positions for realizing a target wireless channel response. Data provides dense sampling of scattering parameters across mechanical configurations for four fixed excitation antennas.

Users should only access this superseded version for special cases, such as reproducing studies. If necessary, this version can be accessed by contacting NCEI.* This intermediate product of High-Resolution Infrared Radiation Sounder (HIRS) Brightness Temperature (TB) data is from level 1b HIRS data. The data are converted into a NOAA HIRS Clear-Sky Channel 12 TB CDR at NCDC.

The NOAA Geostationary Operational Environmental Satellite (GOES) series of satellites goal is to monitor the atmosphere for severe weather development such as tornadoes, flash floods, hail storms and hurricanes. The positioning of the GOES satellites at around 36,000 km (22,000 statute miles) above the equator at a fixed position above the earth allowed them to scan large geographic regions of the Western Hemisphere and as frequently as once every half hour.

The Global Precipitation Climatology Project (GPCP) consists of monthly satellite-gauge and associated precipitation error estimates and covers the period January 1983 to the present. For GPCP V3 monthly precipitation, the primary outputs include combined satellite-gauge precipitation rate, combined satellite-gauge precipitation random error, multi-satellite precipitation, wind-loss adjusted gauge precipitation, and probability of liquid phase, among others. The product is archived on a 0.5-degree global grid.

The GPCP Daily analysis is a companion to the GPCP Monthly analysis, and provides globally complete precipitation estimates at a spatial resolution of a half degree latitude-longitude and daily time scale from 1998 to the present. Although derived using both some of the same, but also different, data sets and methods than used in the GPCP Monthly analysis, the GPCP Daily "adds up" to the GPCP Monthly. The GPCP Daily V3.3 analysis is currently computed by the University of Maryland and submitted to NCEI.

This NODC CD-ROM product (NODC-121) contains the time and space distribution of 74,256 ocean stations (temperature, salinity, and oxygen) occupied in the Barents Sea from 1898 to 1993. These data are recorded on CD-ROM in a format designed for use in electronic spreadsheets and/or databases. Monthly maps defining the station distribution over the Barents Sea are given for every year. Monthly mean fields of temperature and salinity distribution for the depths 0, 30, 50, 100, and 200 m, with a grid distance of 10'x30' are plotted using objective analysis techniques.

This CD-ROM, NODC-146, contains physical and biological data for the region extending from the Barents Sea to the Kara Sea during 158 scientific cruises for the period 1913-1999. Maps with the temporal distribution of physical and biological variables of the Barents and Kara Seas are presented, with proposed quality control criteria for phytoplankton and zooplankton data. Multiple tables of Arctic Seas species are presented, containing ecological and geographic characteristics for each species, and images of live cells for the dominant phytoplankton species.

Zooplankton, temperature, and salinity from various instruments from multiple ships in the White Sea during the period 1961-1999.

This dataset contains partial pressure of carbon dioxide, water temperature, salinity and other variables collected from surface underway observations during the FerryBox ship Magnolia Seaways ships of opportunity (SOOP) cruises in the North Sea and North Atlantic Ocean from 2025-01-29 to 2025-08-14.
