Hydrometeorology Tools
Browse all available hydrometeorology tools.
Available tools
- Catchment Precipitation Area Term Tool Multiply compatible supplied precipitation depth and area; no runoff coefficient is inferred.
- Evaporimeter Pan Coefficient One Day Tool Supplied pan-coefficient depth scaling with area in matching length units, not a calibrated evaporation forecast.
- Freezing Level Station Height Gap Tool Subtract explicit station height from freezing-level height using a shared vertical datum without predicting precipitation phase.
- Gauge Accumulation Interval Depth Tool Compute an explicit nonnegative gauge increment; a declared reset uses caller-supplied post-reset accumulation only.
- Gauge Undercatch Supplied Wind Factor Tool Caller-supplied multiplicative aerodynamic correction followed by additive wetting and evaporation losses; no instrument-specific wind model is fitted.
- Hourly Weather Forecast Validtime Offset Tool Calculate supplied forecast valid-minus-issue epoch hours without fetching a forecast or resolving local time.
- Hydroclimatic Water Deficit One Month Term Tool One ideal bucket month with water available to ET before overflow; no runoff/infiltration timing or actual ET model is inferred.
- Potential Snowmelt Degreehour Factor Tool Positive degree-hour snowmelt with a supplied calibration coefficient and available SWE cap, not an energy-balance forecast.
- Precipitation Accumulator Reset Difference Tool Calculate one explicit precipitation accumulator increment, using current total after a caller-confirmed zero reset and preserving signed discrepancies otherwise.
- Precipitation Basin Area Weight Return one explicitly supplied subarea precipitation contribution to a compatible total basin area.
- Precipitation Phase Explicit Threshold Gap Tool Apply supplied temperature thresholds as descriptive bins; no precipitation-phase diagnosis or physical transition model is inferred.
- Precipitation Phase Source Confidence Token Tool Preserve explicitly supplied precipitation phase and confidence-source metadata without inferring phase from temperature.
- Precipitation Reporting Window Carry Offset Apply explicit carry-in and carry-out attribution adjustments to a precipitation reporting total without redistributing a time series.
- Precipitation Trace Detection Token Keep explicit trace, measured, and missing precipitation flags separate without assigning a numeric trace amount.
- Radar Bin Time Coverage Factor Tool Observed versus constant-rate full-bin equivalents, explicitly preserving coverage rather than silently filling observations.
- Radar Gauge Bias Pair Compare explicit matched radar and gauge precipitation depths, reporting an undefined gauge-ratio denominator separately.
- Radar Pixel Support Share Tool Calculate radar pixel support share from explicit caller-supplied inputs.
- Radar Rain Rate Supplied Zr Point Tool Invert caller-calibrated Z=a*R^b after converting dBZ to linear Z; no universal precipitation regime is selected.
- Radar Reflectivity Linear Average Pair Tool Average two supplied radar reflectivities with equal weight in linear Z space, then return dBZ using a stable logarithmic calculation.
- Rain Accumulation Clock Gap Tool Calculate rain accumulation clock gap from explicit caller-supplied inputs.
- Rain Gauge Tip Count Half Interval Tool Apply explicitly supplied half-tip allocation flags; no missing rainfall is estimated.
- Rain On Snow Heat Budget Term Tool Rain sensible heat cooling to zero Celsius available for melting snow already at zero, excluding all other energy fluxes.
- Rain Snow Observation Source Code Record a supplied precipitation-phase code and source without inferring phase from temperature.
- Rainfall Accumulation Reset Increment Tool Combine two supplied monotone rainfall accumulation segments around one explicit reset.
- Rainfall Gauge Clock Drift Adjustment Tool Subtract a supplied clock-fast offset plus linear drift evaluated on the recorded-time axis.
- Rainfall Intensity Duration Depth Factor Tool Constant rainfall intensity integration and an explicit effective-runoff fraction.
- Rainfall Interevent Drygap Split Tool Calculate rainfall interevent drygap split from explicit caller-supplied inputs.
- Rainfall Timebin Partial Exposure Term Tool Allocate supplied rainfall-bin depth to explicit observed duration under a uniform-within-bin intensity assumption.
- Rainfall Tip Resolution Uncertainty Bound Tool Tipping-bucket accumulated completed tips with an optional unknown residual below one tip; excludes gauge catch and calibration uncertainty.
- Reference ET Coefficient Label Qualify an explicitly supplied evapotranspiration coefficient reference without providing a crop or reference coefficient.
- Snow Core Water Mass Factor Tool Calculate snow core water mass factor from explicit caller-supplied inputs.
- Snow Layer Refreeze Capacity Term Tool Ideal supplied cold-content/latent-heat mass budget, without a snowpack dynamics forecast.
- Snow Pack Melt Volume Balance Reconcile explicitly supplied snowpack water-equivalent movements, retaining signed discrepancies without a melt model.
- Snow Water Depth Contribution Tool Calculate snow water depth contribution from explicit caller-supplied inputs.
- Snow Water Equivalent Increment Tool Convert an explicit signed snow-depth change to water-equivalent depth using supplied compatible snow and water densities.
- Snow Water Equivalent One Layer Term Tool One layer water-equivalent depth with separately supplied liquid depth; snowDensity must exclude liquid already represented by that extra term.
- Snowpack Layer Water Ratio Tool Calculate snowpack layer water ratio from explicit caller-supplied inputs.
- Snowpack Liquid Water Retention Share Tool Instantaneous liquid bucket with a supplied pore-volume retention fraction, not a snow permeability or percolation model.
- Soil Frost Freezing Degreehour Term Tool Cold degree-hour exposure with an explicit index multiplier, without a frost-depth or latent-heat model.
- Storm Gap Boundary Policy Tool Resolve a caller-supplied inter-event dry-gap convention without selecting a storm separation threshold.
- Storm Hyetograph One Bin Volume Term Tool One precipitation-bin volume and equivalent uniform water input rate, without a runoff routing model.
- Storm Inter Event Gap Compare a supplied dry interval with an explicit inclusive storm-separation rule without selecting a storm definition.
- Storm Total Missing Interval Fraction Tool Calculate supplied storm observation missing-duration fraction and observed remainder without estimating missing rainfall.
- Tippingbucket Siphon Reset Count Adjustment Tool Add an explicitly supplied lost-tip correction to a tipping-bucket count without detecting resets or choosing bucket volume.
- Weather Forcing Accumulation Offset Difference an explicit forcing accumulation under a caller-supplied reset flag and reset base.
- Wetbulb Precipitation Reference Temperature Gap Tool Compare caller-supplied wet/dry-bulb observations; no psychrometric wet-bulb estimate or weather classification is made.
