  4. PAPER Choose one atmospheric or oceanic physical property Describe remote sensing sensors that can measure this quantity either directly or indirectly Describe applications Tell me what property/parameter by July 30. Everyone will have a unique parameter/property. Paper - 5 pages, not including figures if you need them. DUE: SEPT. 21 Examples: SST Winds; boundary layer or upper levels Clouds Ice Ocean Currents Ocean temperatures Ocean biology Aerosols Water vapor/precipitation Waves

  5. Course ObjectivesThe primary objective of this course is to understand how radiance measurements at the top of the atmosphere provide information about characteristics of the atmosphere and ocean. To that end we must ... • understand the basic physical characteristics of radiation: • and what approximations are useful for understanding radiance at the top of the atmosphere for different wavelength regions. • review a brief history of environmental satellites and understand their orbit and sensor characteristics. • understand the application of satellite measurement techniques to the detection of: • clouds (aerosols) and their characteristics from visible and IR measurements, • oceanic productivity through ocean color measurements, • temperature profiles from multispectral IR and MW measurements • atmospheric constituents (H2O(v) and O3) from multispectral IR and MW measurements • sea surface temperature from IR measurements • precipitation, wind speed, water vapor and liquid water from passive microwave measurements, • sea state, sea surface height, wave height, currents, winds and other properties from active microwave measurements.

  6. Advantages /Disadvantages • Advantages of remote sensing: • global/large spatial coverage, • generally good repeat temporal coverage, • rapid/instantaneous survey (snapshot), • measurements where in-situ measurements are not available or difficult to make for geographical and political/military reasons, • measurements do not interfere with the process being measured, etc. Remote sensing is the acquisition of geophysical/environmental data from sensing devices remote from the feature of interest. Usually we are not measuring directly the parameter of interest, we infer it from other properties (examples: astrophysics (properties/composition/structure of planets/stars from the radiation they emit), ocean tomography (variations in sound propagation to estimate temperature/density variability in the ocean). In satellite remote sensing the reception of EM energy at a sensor located in space is used to estimate physical (and also biochemical) processes occurring in the earth's atmosphere, land and ocean. • Disadvantages: • cannot measure all parameters (ex: SST yes, SSS no yet), • opacity of atmosphere, • limited resolution in both horizontal and vertical directions, • less accurate than in-situ, • in-situ verification/calibration necessary but sometime difficult, etc. • Parameters that are (or have been) successfully sensed remotely from satellite: • Ocean: color (chlorophyll), SST, sea state, surface height, wave height, internal waves, etc. ; geoid • Atmosphere: surface and higher winds, aerosols, ozone, clouds, CO2, precip. water, etc. ; rain rate • The remote sensing course is one of the most useful and relevant for your career . Military applications include: • Visible: ocean color , turbidity of coastal waters (amphibious operations) , clouds • Infrared: sea surface temperature; input for weather models • Passive and Active Microwave: sea surface characteristics, currents, winds, significant wave height, ice coverage, etc. • geoid

  16. Autonomous Temperature and Salinity profiling http://hrp.whoi.edu/floats/spalace_overv.html Salinity Profiling Autonomous LAgrangian Circlulation Explorer (S-PALACE) floats are new tools for acquiring temperature and salinity profiles in remote or inhospitable regions. These autonomous floats have the advantage that once deployed, no ships or people are required on site to obtain the measurements. The data is collected by the float and telemetered back to land via satellite link. Floats can last as long as 150 profiles or more, giving a 4-5 year lifetime on a two-week cycle. By analysing the data as it is returned, we can learn more about the characteristics of the upper ocean's heat and salt content as well as its circulation. S-PALACE data are expected to be important inputs to predictive ocean-atmosphere coupled models in the future, as greater numbers are deployed in the global ocean.
