Lays the groundwork for a Day 2-7 propagation outlook driven by NCEP GEFS ensemble-mean output, picking up where HRRR's 18-hour horizon leaves off. - GefsClient: NOMADS URL builder, forecast-hour list (3h to +240, 6h to +384), ensemble-mean message inventory, and a Magnus dewpoint derivation (pgrb2a publishes RH rather than Td) - gefs_profiles table + GefsProfile schema mirroring hrrr_profiles so the scorer can run over rows from either source - Weather.upsert_gefs_profile/1 and upsert_gefs_profiles_batch/1 No worker or UI yet — those land in follow-up commits.

defmodule Microwaveprop.Weather.GefsProfile do

@moduledoc """
|
|
Grid-point atmospheric profile sourced from NCEP GEFS ensemble-mean
|
|
(`geavg`) pgrb2a 0.5° output. Mirrors the shape of
|
|
`Microwaveprop.Weather.HrrrProfile` so the existing scorer can run
|
|
over rows from either source for a given `valid_time`.
|
|
|
|
GEFS publishes relative humidity rather than dewpoint, so
|
|
`surface_dewpoint_c` on these rows is derived by
|
|
`Microwaveprop.Weather.GefsClient.dewpoint_from_rh/2` at ingest time.
|
|
HPBL is not in the pgrb2a product; that column intentionally doesn't
|
|
exist here.
