havsnivåmätning
Havsnivåmätning is the process of measuring the height of the sea surface relative to a fixed reference point. This measurement is crucial for understanding climate change, coastal erosion, and predicting potential flooding. Historically, tide gauges have been the primary method for determining sea level. These devices, often located on piers or the coast, record the rise and fall of the tide over time, providing long-term data series.
In more recent decades, satellite altimetry has revolutionized havsnivåmätning. Satellites equipped with radar altimeters send pulses
Data from both tide gauges and satellites are analyzed to identify trends, assess the rate of sea
