Digital Lunar Orbiter Photographic Atlas of the Moon

LPI

Subject(s)
Content type(s)
Country
The Lunar Orbiter Photographic Atlas of the Moon by Bowker and Hughes (NASA SP-206) is considered the definitive reference manual to the global photographic coverage of the Moon. The images contained within the atlas are excellent for studying lunar morphology because they were obtained at low to moderate Sun angles. The digital Lunar Orbiter Atlas of the Moon is a reproduction of the 675 plates contained in Bowker and Hughes. The digital archive, however, offers many improvements upon its original hardbound predecessor. Multiple search capabilities were added to the database to expedite locating images and features of interest. For accuracy and usability, surface feature information has been updated and improved. Lastly, to aid in feature identification, a companion image containing feature annotation has been included. The symbols on the annotated overlays, however, should only be used as locators and not for precise measurements. More detailed information about the digital archive process can be read in abstracts presented at the 30th and 31st Lunar and Planetary Science Conferences.

CBEO

Subject(s)
Content type(s)
Country
The Chesapeake Bay Environmental Observatory (CBEO) is a prototype to demonstrate the utility of newly developed Cyberinfrastructure (CI) components for transforming environmental research, education, and management. The CBEO project uses a specific problem of water quality (hypoxia) as means of directly involving users and demonstrating the prototype’s utility. Data from the Test Bed are being brought into a CBEO Portal on a National Geoinformatics Grid developed by the NSF funded GEON. This is a cyberinfrastructure netwrok that allows users access to datasets as well as the tools with which to analyze the data. Currently, Test Bed data avaialble on the CBEO Portal includes Water Quality Model output and water quality monitorig data from the Chesapeake Bay Program's CIMS database. This data is also available as aggregated "data cubes". Avaialble tools include the Data Access System for Hydrology (DASH), Hydroseek and an online R-based interpolator.

Ozone Mapping and Profiler Suite

OMPS

Subject(s)
Content type(s)
Country
The Ozone Mapping and Profiler Suite measures the ozone layer in our upper atmosphere—tracking the status of global ozone distributions, including the ‘ozone hole.’ It also monitors ozone levels in the troposphere, the lowest layer of our atmosphere. OMPS extends out 40-year long record ozone layer measurements while also providing improved vertical resolution compared to previous operational instruments. Closer to the ground, OMPS’s measurements of harmful ozone improve air quality monitoring and when combined with cloud predictions; help to create the Ultraviolet Index, a guide to safe levels of sunlight exposure. OMPS has two sensors, both new designs, composed of three advanced hyperspectralimaging spectrometers.The three spectrometers: a downward-looking nadir mapper, nadir profiler and limb profiler. The entire OMPS suite currently fly on board the Suomi NPP spacecraft and are scheduled to fly on the JPSS-2 satellite mission. NASA will provide the OMPS-Limb profiler.
