Atmosphere

Understanding the composition of Earth’s atmosphere is important for both air quality and climate change. The atmosphere is changing. Some of the gases that now enter the atmosphere from both human activity and natural processes are hazardous to our health. Rising greenhouse gas concentrations are causing Earth’s climate to warm.
Satellites allow NASA to identify sources of air pollution and track how chemicals move through the atmosphere. They help measure how much greenhouse gases are causing Earth to warm, and how warming is changing the atmosphere.
 
Terra and Atmospheric Composition
Terra is the first satellite to provide integrated measurements of the processes connecting the atmosphere to emissions from activity on the ground. For example, Terra instruments measure both fires and smoke. In particular, Terra instruments measure aerosols (particles in the atmosphere) and carbon monoxide.
 
Aerosols
Aerosols come from a variety of sources, both natural and anthropogenic. MISR and MODIS both measure the concentration of aerosols in the atmosphere and, in some cases, provide insight into the sources of aerosol pollution. MISR can record the height of aerosol plumes in the atmosphere. Aerosols can shade the Earth by reflecting sunlight. CERES measures how much energy aerosols reflect or absorb.
 
Carbon Monoxide
While carbon monoxide (CO) is not itself a greenhouse gas, CO is chemically linked with methane, ozone, and carbon dioxide, and therefore impacts both climate and air quality.  Primary sources of CO include fossil-fuel burning, biomass burning and methane oxidation.

Global Warming
Clouds cause cooling by reflecting solar energy, but they also cause warming by absorbing infrared energy (like greenhouse gases) from the surface when they are over areas that are warmer than they are. In our current climate, clouds have a cooling effect overall, but that could change in a warmer environment.

Clouds can both cool the planet (by reflecting visible light from the sun) and warm the planet (by absorbing heat radiation emitted by the surface). On balance, clouds slightly cool the Earth. (NASA Astronaut Photograph STS31-E-9552 courtesy Johnson space Center Earth Observations Lab.)

If clouds become brighter, or the geographical extent of bright clouds expands, they will tend to cool Earth’s surface. Clouds can become brighter if more moisture converges in a particular region or if more fine particles (aerosols) enter the air. If fewer bright clouds form, it will contribute to warming from the cloud feedback.
See Ship 
	Tracks South of Alaska to learn how aerosols can make clouds brighter.
Clouds, like greenhouse gases, also absorb and re-emit infrared energy. Low, warm clouds emit more energy than high, cold clouds. However, in many parts of the world, energy emitted by low clouds can be absorbed by the abundant water vapor above them. Further, low clouds often have nearly the same temperatures as the Earth’s surface, and so emit similar amounts of infrared energy. In a world without low clouds, the amount of emitted infrared energy escaping to space would not be too different from a world with low clouds.

Clouds emit thermal infrared (heat) radiation in proportion to their temperature, which is related to altitude. This image shows the Western Hemisphere in the thermal infrared. Warm ocean and land surface areas are white and light gray; cool, low-level clouds are medium gray; and cold, high-altitude clouds are dark gray and black. (NASA image courtesy GOES Project Science.)

High cold clouds, however, form in a part of the atmosphere where energy-absorbing water vapor is scarce. These clouds trap (absorb) energy coming from the lower atmosphere, and emit little energy to space because of their frigid temperatures. In a world with high clouds, a significant amount of energy that would otherwise escape to space is captured in the atmosphere.
Natural Resource Damages (NRD) - NYSDEC
From prominent resources, such as Long Island Sound, the Hudson River, the Adirondack Park, and Niagara Falls to small rural ponds, creeks, wetlands and municipal parks - the Department of Environmental Conservation (DEC)'s mission is to conserve, improve and protect all of the natural resources of New York State for the benefit of its citizens. The Commissioner of Environmental Conservation is the Trustee for the natural resources of the State of New York, having been so designated by the Governor. In order to aid the Commissioner in fulfilling his Trustee obligations, DEC's Natural Resource Damages Staff seek to recover damages from responsible parties when natural resources are injured and use such damages to restore or replace those resources.What are Natural Resource Damages?When a spill or release of contaminants into the environment results in injuries to natural resources, Natural Resource Damages (NRD) are sought from the party or parties legally responsible in order to restore the injured natural resources and compensate the public. The goal of an NRD claim is the restoration, replacement, or acquisition of the equivalent of the injured resources, and compensation for past and future lost services that the injured resources would have provided had they not been injured by the release. Damages also include the cost of the damage assessment. "Natural resources" that may be the subject of an NRD claim include, but are not limited to, land, water, groundwater, drinking water supplies, air, fish, wildlife, and biota.Legal AuthorityRecovery of damages for injury to natural resources is authorized by both federal and state law. The federal laws are: the Superfund law (Comprehensive Environmental Remediation, Compensation and Liability Act, or CERCLA), the Oil Pollution Act, and the Clean Water Act. The State laws are: the Environmental Conservation Law (ECL), the Navigation Law and common law. CERCLA requires the U.S. president and each state governor to designate federal and state officials who will act on behalf of the public as trustees for natural resources. The Governor has designated the Commissioner of Environmental Conservation as the Trustee for New York's natural resources. Frequently, DEC is a co-trustee with the federal Trustees from the National Oceanic and Atmospheric Administration (NOAA) and the Department of the Interior (DOI), among others, and, in certain cases, with Native American tribes.
