Field Campaigns

MLO is the site of the longest running measurements of atmospheric CO2, begun in the late 1950s by Charles Keeling. MLO offers a unique testing environment for the Mini-LHR, as the altitude helps ensure the atmosphere sampled represents the “background” signal of the atmosphere.

Space Missions

geoXo

NOAA’s Geostationary Extended Observations (GeoXO) satellite system will expand observations of Earth that the GOES-R Series currently provides from geostationary orbit. The information that GeoXO supplies will address emerging environmental issues and challenges regarding weather, the ocean, and the climate that threaten the security and well-being of everyone in the Western Hemisphere. NOAA expects that GeoXO will begin operating in the early 2030s as the GOES-R Series nears the end of its operational lifetime.

NOAA’s latest generation of Geostationary Operational Environmental Satellites (GOES), known as the GOES-R Series, is the nation’s most advanced fleet of geostationary weather satellites. Geostationary satellites circle the Earth in geosynchronous orbit, which means they orbit the Earth’s equatorial plane at a speed matching the Earth’s rotation.

Launch

The Sun is the predominant source of energy input to Earth. Solar radiation ensures the maintenance of the appropriate range of temperatures for the sustenance of life on Earth, by driving land surface heating, plant productivity, and oceanic and atmospheric circulations. Because of the Sun’s dominant influence on Earth’s function, it is important to accurately measure the solar input to Earth or solar irradiance. Measurement of the total solar irradiance (TSI) is essential for quantifying Earth’s energy budget.

Data Files

The Earth as a whole responses to external forces as an elastic body. Putting additional mass on the Earth's surface causes crust deformation. Changes of loading mass result in variable displacements of Earth's surface.

The CDDIS was established in 1982 as a dedicated data bank to archive and distribute space geodesy related data sets. Today, the CDDIS archives and distributes mainly Global Navigation Satellite Systems (GNSS, currently Global Positioning System GPS and GLObal NAvigation Satellite System GLONASS), laser ranging (both to artificial satellites, SLR, and lunar, LLR), Very Long Baseline Interferometry (VLBI), and Doppler Orbitography and Radio-positioning Integrated by Satellite (DORIS) data for an ever increasing user community of geophysists.

Instruments

EPIC (Earth Polychromatic Imaging Camera) is a 10-channel spectroradiometer (317 – 780 nm) onboard DSCOVR (Deep Space Climate Observatory) spacecraft. EPIC provides 10 narrow band spectral images of the entire sunlit face of Earth using a 2048x2048 pixel CCD (Charge Coupled Device) detector coupled to a 30-cm aperture Cassegrain telescope.

To improve VLBI data to meet increasingly demanding requirements, an end-to-end redesign called the VLBI Global Observing System (VGOS, formerly VLBI2010) is in progress. The key concepts are a broadband signal acquisition chain (2-14 GHz) with digital electronics and fast, small antennas.

Models

CIRC is in many respects the successor to the seminal ICRCCM (Intercomparison of Radiation Codes in Climate Models) effort that spanned the late 80's - early 00's. CIRC distinguishes itself from ICRCCM by its emphasis on using observations to build its catalog of cases.
