Angstromiq is a precision atmospheric optics calculator that transforms spectral extinction data into meaningful aerosol insights. Built for researchers, students, and environmental analysts, it calculates the Ångström exponent and optical depth at a reference wavelength to reveal how aerosols influence light scattering and climate behavior. Its intuitive interface combines scientific accuracy with aesthetic design, featuring gradient visuals inspired by atmospheric spectra and easy-to-use numeric fields for clean data entry. With real-time validation, quick computation, and export-ready results, Angstromiq bridges lab and field studies by offering a compact, reliable tool for understanding aerosol size distribution and optical characteristics across the visible spectrum.
