Synthetic firn seismic velocity profiles

Seismic Velocity profiles for firn generated using the Herron and Langway firn densification model. Velocity models for the 'true' subsurface, the starting velocity model used for FWI, and the final updated velcoity model from FWI are included.本数据集包含采用赫伦-兰韦粒雪致密化模型（Herron and Langway firn densification model）生成的粒雪（firn）地震速度剖面；同时涵盖了“真实”地下介质的速度模型、用于全波形反演（FWI）的初始速度模型，以及经FWI最终更新得到的速度模型。
