Hi Chris,
My met data is the only input boundary condition file I have and it doesn't change throughout the simulation, yet I consistently see a change in the output around May 8-10 that I can't explain/didn't intend. For example, the mean temperatures of a center curtain (shown in the second figure) follow a linear trend but there is a kink around May 8-10. I've also observed changes in trends for velocity and blue ice at these dates as well. Do you have any suggestions that could point me in the right direction for what could be causing this? Let me know if there's any more details I could share about the simulation to help make this more clear.
Thank you,
Dana
