Radiometric DatingGeochronologySimulate ideal model ages and isotopic composition for C-14, U-Pb, K-Ar, and Rb-Sr, with an interactive curve and geological timelineBragg DiffractionCrystallography and petrologyCalculate the diffraction angle, interplanar distance, or X-ray wavelength using Bragg's Law with an interactive crystal lattice animation.Condensation Level LCL/CCLMeteorology and climatologyEstimate LCL, CCL and convective temperature (Tc) from temperature, humidity and environmental lapse rate. Linear model with heights above the surface (AGL).Psychrometric Chart & Moist Air PropertiesMeteorology and climatologyCalculate humidity ratio, dew point, liquid-water wet bulb, enthalpy and density from temperature, one humidity input and pressure or altitude.P- and S-Wave VelocitiesGeophysics and oceanographyCalculate Vₚ, Vₛ, Vₚ/Vₛ, and Poisson's ratio in a homogeneous medium. Estimate approximate epicentral distance from S−P under a shallow-focus assumption.Tidal Harmonic SynthesisGeophysics and oceanographyReconstruct sea level η(t) by summing the M2, S2, K1 and O1 constituents over mean level H₀. Compute high/low waters, tidal range and the Courtier form factor with an interactive time-series visualization.Holdridge Life ZonesMeteorology and climatologyClassifies climate into one of the 38 Holdridge life zones from mean annual temperature and precipitation. Computes biotemperature, potential evapotranspiration (PET), PET ratio, humidity province and latitudinal region, with an interactive logarithmic triangular diagramTAS Volcanic Rock ClassificationCrystallography and petrologyClassify a volcanic rock into the 15 fields of the IUGS TAS diagram from SiO₂, Na₂O and K₂O. Normalises the composition to an anhydrous basis, resolves the sodic and potassic sub-names of the trachytic series, reports compositions falling on a boundary and computes the distance to the nearest field limitMichel-Lévy Birefringence ChartCrystallography and petrologyRelate thickness, birefringence and optical retardation; display the order and maximum normal reference colour on the Michel-Lévy chart.Piper Diagram and Hydrochemical FaciesHydrology and hydrochemistryConvert Ca, Mg, Na, K, HCO₃, CO₃, SO₄, Cl and NO₃ to meq/L; project one or more samples on a Piper diagram, classify Palmer properties, and calculate charge balance, hardness and ionic strength.Köppen climate classification and climographMeteorology and climatologyClassify a climate from 12 monthly temperature and precipitation normals; explore its letters, thresholds and dry months.
