Abstract We introduce three families of diagonal reflection principles for matrices stationary sets ordinals. analyze both their relationships among themselves and with other known simultaneous reflection, the strong principle, existence square sequences.

Surface water/ice dynamic monitoring is crucial for many purposes, such as water resource management, agriculture, climate change, drought, and flood forecasting. New advances in remote sensing satellite data have made it possible to monitor the surface dynamics both spatially temporally. However, there are challenges when using these data, availability of valid imagery, cloud contamination iss...
