Struct AtmoSock 

pub struct AtmoSock { /* private fields */ }

Downrange-segmented atmosphere handler (MBA-1137), the density analogue of crate::wind::WindSock.

Holds a set of station-referenced atmosphere zones ordered by their until_distance_m threshold and answers a stateless downrange lookup (AtmoSock::atmo_for_range).

The zone T/P/H are the base (shooter-altitude) conditions for that stretch of range; the solver swaps them into the SAME get_local_atmosphere altitude-lapse pipeline that a single-station solve uses, so the downrange (X) zone and the vertical (Y) altitude lapse compose orthogonally without double-counting (the zone sets the base tuple, the lapse multiplies on top of it).

Implementations

impl AtmoSock

pub fn new(segments: Vec<AtmoSegment>) -> Self

Create a new AtmoSock from station-referenced atmosphere zones.

Each segment is (temp_c, pressure_hpa, humidity_percent, until_distance_m). Segments are sorted by until_distance_m (NaN thresholds are ordered last, matching WindSock::new).

pub fn is_empty(&self) -> bool

True when this sock carries no zones (a lookup falls back to sea-level ISA).

pub fn atmo_for_range(&self, downrange_m: f64) -> (f64, f64, f64)

Stateless downrange lookup of the active zone’s (temp_c, pressure_hpa, humidity_percent).

Selection matches crate::wind::WindSock::vector_for_range_stateless: the first segment whose until_distance_m STRICTLY exceeds downrange_m wins (thresholds are upper-exclusive). Unlike wind — which returns zero past the last threshold — the LAST zone is used for any distance at or beyond the final threshold (there is no “zero atmosphere”). An empty sock returns the sea-level ISA reference (15 C, 1013.25 hPa, 0% RH).

This is stateless and safe for numerical integration (the same X may be queried repeatedly or out of order across RK substeps).
