  Microwave radiometers: These sensors detect the microwave radiation emitted by water vapor in the atmosphere, allowing the estimation of the water vapor concentration.  Infrared sensors: Measure sea surface temperatures and detect clouds, which help estimate the rate of evaporation.  Scatterometers: Measure wind speeds over the ocean surface, which influence the evaporation rate.  ------------------------------------------------------------------------------------------- -----  Transition to Cleaner Energy Sources  Renewable Energy: Promote the use of renewable energy sources such as solar, wind, hydropower, and geothermal, which do not produce SO₂ or NOₓ.  Nuclear Energy: While nuclear energy has its own challenges, it produces no SO₂ or NOₓ emissions and can be part of an energy strategy to reduce acid rain.  Natural Gas: Switch from coal to natural gas, which burns cleaner and produces less sulfur dioxide and nitrogen oxides.  b. Install Emission Control Technologies  Scrubbers: Install flue-gas desulfurization (FGD) units, also known as "scrubbers," in power plants and industrial facilities to remove SO₂ from exhaust gases before they are released into the atmosphere.  Selective Catalytic Reduction (SCR): This technology reduces NOₓ emissions from vehicles and industrial processes by injecting ammonia or urea into the exhaust system, converting NOₓ into harmless nitrogen and water vapor.  Low-NOₓ Burners: These burners minimize NOₓ production during combustion in industrial boilers and furnaces.  c. Promote Cleaner Transportation  Electric Vehicles (EVs): Encourage the use of electric vehicles, which produce zero tailpipe emissions and thus no SO₂ or NOₓ.  Public Transport: Improve public transportation infrastructure to reduce the number of private vehicles on the road, thereby cutting emissions.  Regulations on Vehicle Emissions: Implement stricter emission standards for vehicles to limit NOₓ emissions, such as the adoption of catalytic converters in vehicles.  d. Energy Efficiency and Conservation  Energy Efficiency: Encourage energy efficiency in industries, homes, and transportation to reduce overall fuel consumption, leading to fewer emissions.  Energy Conservation: Implement programs and incentives for individuals and businesses to reduce energy usage, like using energy-efficient appliances or improving insulation in buildings.  2. Liming of Affected Water Bodies and Soil  To mitigate the effects of acid rain on lakes, rivers, and soils, neutralizing agents like lime (calcium carbonate) can be applied to counteract the acidity.  a. Lime Application to Lakes and Streams  How it works: Limestone or lime (CaCO₃) is added to acidified lakes, rivers, or streams to neutralize the acidity and restore a more balanced pH level, making the water more hospitable for aquatic life.  Benefits: Liming helps to reduce the toxic effects of metals, like aluminum, which are mobilized in acidic environments and harm aquatic organisms.  Limitations: Liming is a temporary solution that requires repeated applications, as acid rain can continue to acidify water bodies.  b. Soil Liming  How it works: Agricultural lime (calcium carbonate) or other alkaline substances are applied to acidic soils to raise the pH and reduce the impact on plant growth.  Benefits: Neutralizes soil acidity, improving nutrient availability and promoting healthier vegetation.  Limitations: Like water liming, this is a temporary solution and can be labor-intensive on a large scale.  3. Restoration of Ecosystems  Restoring ecosystems damaged by acid rain can help rehabilitate the natural environment over time.  a. Reforestation  Plant Acid-Resistant Tree Species: In areas where acid rain has damaged forests, replanting with tree species that are more tolerant to acidic soils, such as certain coniferous species, can help the ecosystem recover.  Soil Amendment: Applying lime or other materials to forest soils can help restore nutrient levels and improve soil health, allowing vegetation to recover.  b. Restoring Aquatic Life  Stocking Fish and Aquatic Life: After liming water bodies, fish and other aquatic species can be reintroduced to help rebuild biodiversity and restore the ecological balance.  Habitat Restoration: Efforts like improving wetlands and riparian zones (areas along riverbanks) can help ecosystems recover from acidification damage.  4. Regulatory and Policy Measures  Governments and international bodies have developed regulations and treaties aimed at reducing emissions and mitigating the effects of acid rain.  a. Clean Air Act (U.S.)  The U.S. Clean Air Act introduced an Acid Rain Program that has led to significant reductions in SO₂ and NOₓ emissions, particularly through a cap-and-trade system that limits emissions from power plants.  b. International Agreements  The Gothenburg Protocol: An international agreement under the UNECE Convention on Long-range Transboundary Air Pollution, aimed at reducing acid rain by setting emission reduction targets for SO₂ and NOₓ for participating countries.  EU Directives: The European Union has set strict standards on emissions from power plants, vehicles, and industrial facilities to curb the pollutants that cause acid rain.  5. Public Awareness and Education  Raising public awareness about the causes and effects of acid rain, as well as the importance of reducing emissions, can encourage individuals and communities to take action.  a. Educational Campaigns  Promote the understanding of how individual actions (e.g., reducing energy consumption, using cleaner energy, and adopting electric vehicles) contribute to reducing acid rain.  b. Incentives for Green Energy and Transportation  Governments can provide tax incentives or rebates for households and industries to adopt cleaner energy technologies (e.g., solar panels) and transportation options (e.g., electric cars).  6. Monitoring and Research  Continued monitoring of acid rain levels and the health of ecosystems affected by it is essential for adapting strategies to control and mitigate its impact.  a. Air Quality Monitoring  Set up networks of air quality monitoring stations to track SO₂, NOₓ, and particulate matter levels in different regions.  Example: The National Atmospheric Deposition Program (NADP) in the U.S. monitors precipitation and air chemistry across the country.  b. Environmental Research  Support ongoing research into the long-term impacts of acid rain on ecosystems, agriculture, human health, and infrastructure.   Develop new technologies for emission reduction and ecosystem restoration.  7. Protecting Infrastructure  Acid rain corrodes buildings, bridges, and monuments, especially those made of limestone and marble. Measures can be taken to protect these structures.  a. Protective Coatings  Apply weather-resistant coatings to buildings and monuments made of vulnerable materials (e.g., limestone and marble) to shield them from acid rain.  b. Regular Maintenance  Increase the frequency of maintenance and cleaning to remove acid rain deposits and reduce long-term damage.  
