The DKup24 uplift model for Denmark.

A regional land uplift model for Denmark has been derived from geodetic data from the past century. The model reflects deformations in the national height systems and may be used to dynamically extend the quality of DVR90 into the future. Also, the uplift model may play an important role in assessing impacts of climate scenarios when planning future facilities such as coastal protection.The model is determined using an empirical approach and data from the three national precision levelling campaigns, tide gauges, and permanent GNSS reference stations. The NKG2016GIA model by Steffen et al. (2016) is used as reference mode. The DKup24 uplift model forms a so-called long-term release in the modelling of the land uplift in Denmark where the classical data are used. Since the release of the previous model in 2016, the data has been reassessed to form a consistent data set.More details will be provided soon.The model is released in two versions:The DKup24abs.* reflecting uplift relative to the ellipsoid, andThe DKup24geo.* reflecting uplift relative to the geoid.In addition an error field is provided in the file DKup24err.*All files are available in TIF, GTX, Gravsoft GDR, and combined in XYZ

基于过去一个世纪的地理测量数据，丹麦地区性地面抬升模型已得以构建。此模型映射了国家高程系统中的变形，并可动态地提升DVR90数据集在未来时期的质量。此外，该抬升模型在规划未来设施如海岸防护等时，对评估气候变化情景的影响亦发挥着举足轻重的作用。模型采用经验方法，结合了三次国家精密水准测量、潮位计和永久性全球导航卫星系统参考站的数据进行确定。Steffen等（2016年）提出的NKG2016GIA模型作为参考模式。DKup24抬升模型在丹麦地面抬升建模领域构成了所谓的长期发布版本，其中采用了经典数据。自2016年发布前一个模型以来，数据已重新评估，以形成一致的数据集。更多详情将随后提供。模型以两个版本发布：DKup24abs.*，反映相对于椭球体的抬升，以及DKup24geo.*，反映相对于大地水准面的抬升。此外，在DKup24err.*文件中提供了误差字段。所有文件均以TIF、GTX、Gravsoft GDR格式提供，并综合为XYZ格式。
