Support for complex terrain

[rcjackson]

Milos Rompar has been using PyDDA to retrieve winds from a radar/lidar network where the domain includes a 1400 m hill where the radar is. Since we assume flat terrain in our retrieval, there would definitely be some inaccuracy in the winds since we do not consider the terrain.

I think adding a complex terrain constraint would be as simple as constraining the gradient of the cost function to be zero at and below the ground. I'm looking for people to work with on implementing such terrain maps so that we can test out such a feature.

I'm going to sign up to work on this. Definitely an issue for CACTI-RELAMPAGO. I'll keep you posted.

@swnesbitt did you make progress on this?

No, probably not in the near future either From: Max Grover ***@***.***> Date: Wednesday, July 6, 2022 at 2:04 PM To: openradar/PyDDA ***@***.***> Cc: Nesbitt, Stephen ***@***.***>, Mention ***@***.***> Subject: Re: [openradar/PyDDA] Support for complex terrain (#52) @swnesbitt<https://urldefense.com/v3/__https:/github.com/swnesbitt__;!!DZ3fjg!8ByoRObAkAI_yqc09HmUz2qnO_T53Q9gzcRAwheMnzON_dKPLHXIABpK2OYPxkOh09Fqrj8W6o2VkDMC66zcjSEIUnE$> did you make progress on this? — Reply to this email directly, view it on GitHub<https://urldefense.com/v3/__https:/github.com/openradar/PyDDA/issues/52*issuecomment-1176572604__;Iw!!DZ3fjg!8ByoRObAkAI_yqc09HmUz2qnO_T53Q9gzcRAwheMnzON_dKPLHXIABpK2OYPxkOh09Fqrj8W6o2VkDMC66zcdvnKTXc$>, or unsubscribe<https://urldefense.com/v3/__https:/github.com/notifications/unsubscribe-auth/AAZC4ECQVEITQSBV7UY4DQDVSXKDPANCNFSM4KJTIZUQ__;!!DZ3fjg!8ByoRObAkAI_yqc09HmUz2qnO_T53Q9gzcRAwheMnzON_dKPLHXIABpK2OYPxkOh09Fqrj8W6o2VkDMC66zcIlRmQXw$>.
