  • Cloudsat CALIPSO
    www.nasa.gov andSpaceAdministration National Aeronautics & CloudSat CALIPSO Clean air is important to everyone’s health and well-being. Clean air is vital to life on Earth. An average adult breathes more than 3000 gallons of air every day. In some places, the air we breathe is polluted. Human activities such as driving cars and trucks, burning coal and oil, and manufacturing chemicals release gases and small particles known as aerosols into the atmosphere. Natural processes such as for- est fires and wind-blown desert dust also produce large amounts of aerosols, but roughly half of the to- tal aerosols worldwide results from human activities. Aerosol particles are so small they can remain sus- pended in the air for days or weeks. Smaller aerosols can be breathed into the lungs. In high enough con- centrations, pollution aerosols can threaten human health. Aerosols can also impact our environment. Aerosols reflect sunlight back to space, cooling the Earth’s surface and some types of aerosols also absorb sunlight—heating the atmosphere. Because clouds form on aerosol particles, changes in aerosols can change clouds and even precipitation. These effects can change atmospheric circulation patterns, and, over time, even the Earth’s climate. The Air We Breathe The Air We We need better information, on a global scale from satellites, on where aerosols are produced and where they go. Aerosols can be carried through the atmosphere-traveling hundreds or thousands of miles from their sources. We need this satellite infor- mation to improve daily forecasts of air quality and long-term forecasts of climate change.

  • Cloudsat Overview
    CloudSat Overview CloudSat will provide, from space, the first global survey of cloud profiles and cloud physical properties, with seasonal and geographical variations, needed to evaluate the way clouds are parameterized in global models, thereby contributing to improved predictions of weather, climate and the cloud-climate feedback problem. CloudSat will measure the vertical structure of clouds and precipitation from space primarily through 94 GHz radar reflectivity measurements, but also by using a combination of observations from the EOS-PM Constellation of satellites (A-Train). CloudSat will fly in on-orbit formation with the Aqua and CALIPSO satellites, providing a unique, multi-satellite observing system particularly suited for studying the atmospheric processes of the hydrological cycle. 1. Science Objectives • Evaluate the representation of clouds in weather and climate prediction models. CloudSat will provide a global survey of the vertical structure of cloud systems: This vertical structure is fundamentally important for understanding how clouds affect both their local and large-scale atmospheric and radiative environments. • Evaluate the relationship between cloud liquid water and ice content and the radiative properties of clouds. CloudSat will estimate the profiles of cloud liquid water and ice water content. These are the quantities predicted by cloud-process and global-scale models alike and determine practically all important cloud properties, including precipitation and cloud optical properties. CloudSat will provide coincident profile information on the bulk cloud microphysical properties matched to cloud optical properties. Optical properties contrasted against cloud liquid water and ice contents provide a critical test of key parameterizations that enable calculation of flux profiles and radiative heating rates throughout the atmospheric column.

Through relentless advancement of current technologies, NASA is progressing toward a future of seamless mission enabling space communications and navigation. This futuristic, interoperable system will include the development of optical communications, wideband Ka-band, hybrid optical and radio frequency (RF) antennas, user- initiated services (UIS), a cognitive network with disruption-tolerant networking (DTN) capabilities and autonomous navigation. This vision, although vastly complex, will introduce dramatic increases in performance and is already being worked at NASA Headquarters, NASA’s Goddard Space Flight Center, NASA’s Glenn Research Center, and Jet Propulsion Laboratory. Teams from around the country continue to investigate and strive for innovative solutions to the many complex challenges space communications and navigation faces. CURRENT CAPABILITIES For the past 50 years, NASA has primarily used RF to communicate mission data from satellites orbiting in our solar system to data users on Earth.

Current missions must employ many techniques to reduce the data they transmit, such as compressing and pruning datasets, to meet the current restrictions of limited telemetry budgets. Yet future Heliophysics System Observatory missions will produce ever larger data volumes with higher resolution and cadence observations from constellations of satellites spread throughout the heliosphere1. In addition, heliophysics missions often produce data for the Space Weather community that requires a low latency between observation and downlink. In light of current limitations, the infrastructure to ​ receive NASA satellite telemetry must be expanded and modernized to support future science needs and the data-rich missions of the 2050 Heliophysics System Observatory. The current communications landscape: Communications with NASA science missions are primarily routed through the Deep Space Network (DSN), Near Earth Network (NEN), and Space Network (SN) using S, X, and Ka band ​ ​ ​ ​ ​ ​ radio transmissions.
