Satellite Alt Data: Management of the Sea Surface, Wave Height, and Ocean Currents
Satellite alt data is all about the measurement of the elevation and height of the Earth's surface collected from satellite-based altimeters. It is linked to the measurement of the time it takes for an altimetry satellite to bounce a radar or laser pulse off the Earth's face and back to the satellite. The time measurement, added with more parameters, allows for the surface calculation from the height with high precision. It shares valuable details related to the oceans on Earth. It includes the height of the sea surface, wave height, ocean currents, and thickness of the sea ice.
Here are some main applications of satellite altimetry data:
Oceanography: Satellite altimeters calculate sea surface height, which is utilised to study ocean circulation designs, currents, and ocean dynamics. The data helps scientists understand phenomena such as oceanic eddies, events, and the transport of freshwater and heat across the oceans.
Change in Climate
Deforestation Monitoring Space data plays a significant role in monitoring changes in sea level due to climate changes. By tracking the difference in sea surface height over time, experts can measure the rate of sea level rise and its impacts on ecosystems, coastal areas, and human populations.
Forecasting of Weather
The data merged with other meteorological observations assists weather forecasting models. By offering details related to the sea surface height, ocean heat content, and ocean-atmosphere communications, altimetry data contributes to more accurate ideas of tropical cyclones, weather systems, and storm surges.
Marine Navigation
It assists maritime navigation by offering accurate and up-to-date details on sea surface height and bathymetry. The details help ships and vessels avoid hazards. It includes submerged rocks, shallow waters, and sandbars.
Marine Resource Management
It supports the management of marine resources i.e. fisheries. By checking ocean currents and water masses, it helps to find areas with high productivity, place fish aggregations, and support sustainable fishing practices.
Sea Ice Monitoring
The data allows for measuring the sea ice thickness and extent. This information is vital for monitoring climate change in the polar ice caps, knowing the impacts of climate change on Arctic and Antarctic ecosystems, and aiding navigation in icy regions.
Coastal Zone Management
Satellite carbon monitoring assists in monitoring changes in the coastline and coastal erosion. It gives information about sediment transport, shoreline dynamics, and coastal flooding, allowing for better coastal zone management and versioning strategies.
