Satellite altimetry in the coastal zone has the potential to yield a large amount of unique information for coastal management and long-term monitoring of coastal dynamics and sea level change. However, coastal areas are one of major challenges for satellite altimetry due to deterioration of altimeter signals. The analysis of altimeter data close to the coastline is a non-standard procedure that requires the use of high rate waveform data and additional information on environmental corrections and coastline bathymetry. Goal of the project COSELE is to provide improved coastal altimeter data for an improved estimation of sea level variability and of the geoid in coastal areas. As a continuation of the predecessor project ReCoSeTo the aim is to generate more and improved data near coast by applying to the raw waveform data both already developed and new re-tracking algorithms. Dedicated re-trackers will be developed depending on the region and on the satellite. Gridded and along track reanalysis will be compared to local observations at tide gauges. The investigations will focus on selected areas with good a priori information from local data in the Mediterranean Sea, in the German part of the North Sea and in the Thailand/Indonesian Sea. The altimeter analysis is combined with a detailed study of sea level variability and geoid in the German Bight.

沿海地区的卫星测高有可能为沿海管理和长期监测沿海动态和海平面变化提供大量独特的信息。然而，沿海地区由于高度计信号的恶化，是卫星测高面临的主要挑战之一。对靠近海岸线的高度计数据进行分析是一种非标准程序，需要使用高速率波形数据以及有关环境校正和海岸线测深的附加信息。COSELE项目的目标是提供改进的沿海高度计数据，以改进对沿海地区海平面变化和大地水准面的估计。作为前一个项目ReCoSeTo的延续，其目标是通过应用已开发的原始波形数据和新的重新跟踪算法，在海岸附近生成更多和改进的数据。将根据区域和卫星研制专用的再跟踪器。网格化和沿航迹再分析将与本地验潮仪的观测结果进行比较。调查将集中在地中海、北海德国部分和泰国/印度尼西亚海的当地数据中有良好先验资料的选定地区。高度计分析结合了对德国湾海平面变化和大地水准面的详细研究。
