Goal

• To investigate satellites that monitor the
  Earth's atmosphere.

Topic Land

• Terras purpose as a satellite is to observe the
  Earth as it goes around the earth daily.
• Terra Mission- was launched in December 1999, by
  NASA National Aeronautics and Space
  Administration.
• It carries up to 5 different cameras to identify
  certain degrees on the Earth.
• They are
• ASTER Advanced Space borne Thermal Emission and
  Reflection Radiometer
• CERES Clouds and the Earth's Radiant Energy
  System
• MISR Multi-angle Imaging SpectroRadiometer
• MODIS Moderate-resolution Imaging
  Spectroradiometer
• MOPITT Measurements of Pollution in the
  Troposphere

Vocabulary

• Spectroradiometer-- designed to measure the rate
  of imaging of Terras images that it picks up
  every time it takes a picture from space.
• Clouds and the Radiant Energy System (CERES) -It
  is designed to measure the Earth's radiation flux
  and provide estimates of cloud properties of the
  surface of the Earth. definition from wikipedia
  
• Radiation Flux--is a measure of the flow of
  radiation from a given radioactive source.
  definition from wikipedia
• ASTER-- provides high-resolution images of the
  Earth in 14 different wavelengths of the
  electromagnetic spectrum, ranging from visible to
  thermal infrared light. The resolution of images
  ranges between 15 to 90 meter. ASTER data is used
  to create detailed maps of surface temperature of
  land, emissivity, reflectance, and elevation.
  definition from wikipedia
• MOPITT-- designed to monitor changes in pollution
  patterns and its effect in the lower atmosphere
  of the Earth. definition from wikipedia

Terras Studies

• This satellite measures various things
• They are
• clouds
• water vapor
• aerosol particles,
• trace gases,
• terrestrial and
• oceanic properties,
• the interaction between them and their effect on
  atmospheric radiation and climate.
• changes in Earth's radiation budget (a
  measurement of all the inputs and outputs of the
  Earth's radioactive energy),
• together with measurements of changes in
  land/ocean surface and interaction with the
  atmosphere through exchanges of energy, carbon,
  and water. And to make scientists understand
  global climate change a whole lot better.

ASTER

• Provides high-resolution images of the Earth in
  14 different wavelengths of the electromagnetic
  spectrum, ranging from visible to thermal
  infrared light.
• Aster's data is used to create detailed maps of
  surface temperature of land, emissivity,
  reflectance, and elevation.

7
CERES

• It started in orbit around 1999, and the second
  batch of information from CERES, was in May 2002.
• Purpose- to measure the Earth's radiation
  instability and provide estimates of cloud
  properties of the surface of the Earth.

Why I picked.

• I picked this satellite because it is measuring
  several things which I am overly concerned about,
  such as the weather, and mostly about pollution.
  The determination of how much pollution is in the
  air in the Earths Atmosphere.
