- Tasks/Goals:
- Implement Luo, Trishchenko, and Khlopenkov (2008) algorithms for high resolution atmospheric corrections
- Correct geolocation errors via spatially lagged cross-correlation of 2 successive images, e.g., r12(dx,dy)
- Feature tracking (Cayula&Cornillon)
- Tidal current predictions (Padman&Erofeeva)
- Wind observations (Hans Island?)
