Available tools
- Aerosol Optical Depth Slant Factor Tool Use the plane-parallel secant air-mass approximation; curvature and refraction are excluded.
- Atmospheric Column Layer Dry Mass Apply hydrostatic pressure-thickness mass per area and an explicit layer-average water mass fraction to obtain dry-air mass.
- Atmospheric Scale Height Gravity Sensitivity Tool Calculate atmospheric scale height gravity sensitivity from explicit caller-supplied inputs.
- Atmospheric Scale Height Ratio Tool Compare ideal isothermal scale heights R*T/(M*g) using compatible supplied units.
- Atmospheric Science: Cloud Cover Okta Missing Code Label Tool Interpret an explicitly declared cloud-cover coding scheme 0..8 oktas and 9 obscured/missing, retaining missing status separately from unused zero fraction.
- Atmospheric Science: Pressure Thickness Log Layer Mean Tool Compute the logarithmic pressure mean of a positive nonzero layer thickness; this is not an arithmetic midpoint, altitude or hypsometric temperature estimate.
- Atmospheric Science: Rainfall Trace Token To Censored Value Tool Represent a caller-established rainfall trace T as the open-upper interval [0,detectionLimit), preserving censoring rather than replacing it with zero or half a limit.
- Atmospheric Science: Wind Vector Meteorological Sign Tool Resolve meteorological wind-from bearing clockwise from north to eastward/northward velocity components; no gust, height or weather prediction.
- Boundary Layer Height Datum Offset Subtract an explicit ground datum height from a reported boundary-layer height on compatible vertical units.

- Dew Point Versus Frost Point Source Tag Label an explicitly reported liquid-water or ice saturation reference without converting temperatures.
- Dewpoint Depression Observed Term Tool Subtract an explicitly observed dewpoint in matching temperature units; supersaturated observations retain a negative depression.
- Dry Adiabatic Temperature Pressure Ratio Tool Calculate dry adiabatic temperature pressure ratio from explicit caller-supplied inputs.
- Fog Visibility Unit Reference Tag Preserve explicit reported visibility and unit text without classifying fog or making aviation decisions.
- Humidity Mixing Basis Residual Tool Calculate humidity mixing basis residual from explicit caller-supplied inputs.
- Hypsometric Mean Virtual Temperature Factor Tool Compute an isothermal-mean hypsometric layer thickness from explicit virtual temperature and compatible pressures.
- Moist Air Mixing Ratio Vapor Pressure Tool Calculate moist air mixing ratio vapor pressure from explicit caller-supplied inputs.
- Potential Temperature Pressure Sensitivity Tool Differentiate theta=T*(referencePressure/pressure)^exponent at fixed temperature.
- Potential Temperature Reference Ratio Tool Apply a supplied constant dry-adiabatic exponent and explicit reference pressure; no atmospheric profile is inferred.
- Potential Temperature Vertical Gradient Sign Tool Describe the signed potential-temperature gradient between two increasing heights without applying moisture-dependent stability criteria.
- Precipitation Rate Depth Interval Factor Tool Calculate precipitation rate depth interval factor from explicit caller-supplied inputs.
- Pressure Layer Log Midpoint Tool Find the midpoint in log-pressure coordinates using positive supplied pressures.
- Pressure Layer Mass Factor Tool Compute hydrostatic column mass per area from pressure thickness and supplied constant gravity.
- Pressure Level Log Interpolation Weight Calculate an explicit log-pressure coordinate weight between distinct positive pressure levels, permitting extrapolation.
- Pressure Tendency Three Hour Normalizer Tool Calculate pressure tendency three hour normalizer from explicit caller-supplied inputs.
- Pressure Tendency Time Window Weight Tool Pooled pressure-change rate over supplied nonoverlapping intervals, rebased to an explicit duration.
- Radiosonde Height Datum Bridge Tool Bridge explicitly supplied vertical datum offsets without estimating a geoid or atmospheric height model.
- Radiosonde Pressure Inversion Pair Flag an explicit pressure increase between caller-ordered lower and upper sounding levels without attributing instrument error.
- Rain Gauge Catch Correction Factor Tool Calculate rain gauge catch correction factor from explicit caller-supplied inputs.
- Rossby Number Single Scale Term Tool Calculate rossby number single scale term from explicit caller-supplied inputs.
- Shortwave Clearness Index One Observation Tool Calculate shortwave clearness index one observation from explicit caller-supplied inputs.
- Snow Water Equivalent Density Term Tool Calculate snow water equivalent density term from explicit caller-supplied inputs.
- Sounding Level Duplicate Pressure Flag Tool Flag repeated exact pressure values after their first occurrence in a sounding, without imposing a sorting convention.
- Station Pressure Reduction Metadata Label Tool Label the explicitly declared pressure product and reference elevation; no atmospheric pressure reduction is performed.
- Station Wind Height Reference Label Qualify an explicit station wind-measurement height by supplied datum wording without adjusting wind speed.
- Thermal Advection One Horizontal Component Tool Calculate thermal advection one horizontal component from explicit caller-supplied inputs.
- Tropopause Layer Lapse Rate Gap Tool Compare an explicit mean layer lapse rate with a supplied reference; this does not implement a full tropopause definition.
- Virtual Temperature Reference Gap Tool Apply a caller-computed virtual-temperature factor; no humidity approximation or constants are chosen.
- Virtual Temperature Single Humidity Factor Apply an explicit specific-humidity ideal gas-mixture virtual-temperature factor using a supplied vapor-to-dry-air gas-constant ratio and no condensate.
- Visibility Extinction Supplied Coefficient Tool Apply the homogeneous exponential-contrast model using an explicit detection threshold, without selecting a visibility standard.
- Water Vapor Mixing Ratio Specific Humidity Crosswalk Tool Convert water-vapor mass per dry-air mass to mass per total moist-air mass, q = r/(1+r).
- Wind Barb Speed Rounding Code Round explicit wind speed to the nearest five knots and decompose into 50-knot pennants, 10-knot barbs, and a 5-knot half barb.
- Wind Component Calm Flag Tool Calculate wind component calm flag from explicit caller-supplied inputs.
- Wind Direction Calm Undefined Token Tool Suppress an undefined calm direction using a supplied strict speed threshold; zero is a flagged placeholder.
