1	# Compute Aerospace Environment
2
3	Calculate environment properties for aerospace vehicle analysis: atmosphere, gravity, wind, magnetic field, geoid, space weather, planetary ephemeris, and Earth orientation using Aerospace Toolbox functions.
4
5	## When to Use
6
7	- Computing atmospheric properties (temperature, pressure, density, speed of sound)
8	- Calculating gravity vectors or acceleration for any planet
9	- Modeling horizontal wind at altitude
10	- Getting magnetic field components for navigation or compass correction
11	- Computing geoid height or geocentric radius
12	- Reading space weather data for NRLMSISE-00 inputs
13	- Computing planet or Moon positions (ephemeris)
14	- Getting Earth orientation parameters (polar motion, nutation, UT1-UTC, CIP)
15	- Any prompt mentioning: atmosphere model, ISA, COESA, NRLMSISE, pressure, temperature, density, speed of sound, gravity model, WGS84, wind model, HWM, magnetic model, WMM, IGRF, geoid, space weather, solar flux, F10.7, Ap index, planet ephemeris, Moon position, Earth nutation, polar motion, UT1, IERS
16
17	## When NOT to Use
18
19	- Coordinate frame conversions or rotations — use `matlab-convert-aerospace-coordinates`
20	- Orbital mechanics or trajectory propagation (use ephemeris for positions, not orbit propagation)
21	- Aerodynamic coefficient calculations
22	- Simulink environment model blocks — use Aerospace Blockset
23
24	## Workflow
25
26	1. Identify the quantity needed — use the decision table below
27	2. Call the function — follow the patterns in this skill for correct syntax
28	3. Verify results — check units and magnitude are physically reasonable
