Struct NomadsProfile 

#[non_exhaustive]
pub struct NomadsProfile {
    pub latitude_deg: f64,
    pub longitude_deg: f64,
    pub cycle_unix_s: i64,
    pub valid_unix_s: i64,
    pub grid: Grid,
    pub grid_points: [GridPoint; 4],
    pub wind_turn_rad: f64,
    pub surface: NomadsSurface,
    pub levels: Vec<NomadsLevel>,
    pub dropped: Vec<DroppedLevel>,
}

A NOMADS cut read at a site: the ground and the pressure levels above it.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

latitude_deg: f64

The site’s latitude, degrees north.

longitude_deg: f64

The site’s longitude, degrees east.

cycle_unix_s: i64

The run’s start, s since the Unix epoch (UTC).

valid_unix_s: i64

The time the forecast is for, s since the Unix epoch (UTC).

grid: Grid

The cut’s grid.

grid_points: [GridPoint; 4]

The four grid points around the site, with their weights.

wind_turn_rad: f64

The angle the winds were turned by, from the grid’s axes to east and north, rad; 0 when the cut gives them east and north.

surface: NomadsSurface

The ground.

levels: Vec<NomadsLevel>

The pressure levels above the ground, lowest first.

dropped: Vec<DroppedLevel>

The pressure levels left out, highest pressure first.

Implementations

impl NomadsProfile

pub fn parse( body: &[u8], latitude_deg: f64, longitude_deg: f64, ) -> Result<Self, NomadsError>

Reads a NOMADS cut at a site, interpolating bilinearly between the four grid points around it.

Errors

• NomadsError::Grib when the body is not GRIB2 the decoder reads.
• NomadsError::Mixed when its fields differ in grid, cycle or forecast time, and NomadsError::Duplicate when a variable is given twice at one level.
• NomadsError::Outside when the site is not inside the cut’s grid.
• NomadsError::NoSurface when a ground value is not in the cut or has no value around the site, and NomadsError::Height when a height is beyond what the geopotential conversion takes.

pub fn sounding( &self, wind_interpolation: WindInterpolation, ) -> Result<SoundingProfile, AtmosError>

The profile as an atmosphere with its wind: the ground, then each level above it, with relative humidity clamped to [0, 1].

Errors

What SoundingProfile::new refuses: heights not increasing, pressures not decreasing upward, or a value out of range.

Trait Implementations

impl Clone for NomadsProfile

fn clone(&self) -> NomadsProfile

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NomadsProfile

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NomadsProfile

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for NomadsProfile

fn eq(&self, other: &NomadsProfile) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for NomadsProfile

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
