@ljbmyco:matrix.orgLJBMycoHi, I noticed that in 0.16 Atmospheric perturbations were disabled, are there any plans for this to be reintroduced? 13:56:58

@astrojuanlu:matrix.orgastrojuanlu hi Lawrence Bradley , could you expand a bit more? are you using poliastro.earth.EarthSatellite ? 10:19:49
@ljbmyco:matrix.orgLJBMycoYeah I was hoping to, but I noticed that when I try to set an atmosphere I get a NotImplementedError. Is there any way I can use an atmosphere in the propagator? 11:36:30

You can do that using the underlying poliastro.twobody.Orbit objects, have a look at https://docs.poliastro.space/en/stable/examples/Natural%20and%20artificial%20perturbations.html

@astrojuanlu:matrix.orgastrojuanluthe truth is that `poliastro.earth` is not in very good shape and we are not maintaining it as much as we should . you're the first user who uses it to my knowledge, so we'd love to hear your opinion12:25:48
@ljbmyco:matrix.orgLJBMycoOh that is amazing thank you. What I want to look at is how solar cycle affects deorbit time, with that in mind I was hoping to use the nrlmsise-00 atmosphere model from pyatmos, is that something that is possible with poliastro? 12:38:25

We have the COESA models and Jacchia77, but nobody has implemented NRLMSISE-00 yet https://github.com/poliastro/poliastro/issues/702

There's a Python library that provides it https://pynrlmsise00.readthedocs.io and also pyatmos, but it would need a bit of work to integrate with poliastro

@ljbmyco:matrix.orgLJBMycoThanks for your help, doesn't seem like it will be too difficult 13:03:48
