Systems and methods for detection of atmospheric conditions using optical orbital angular momentum (OAM)-based spectroscopy include applying OAM states to a light beam to generate an OAM spectrum, transmitting OAM light beams into an atmosphere, and determining degradation of the generated OAM light beams passing through atmospheric turbulence. A rotation rate of aerosols in the atmosphere is determined by analyzing different frequency shifts in OAM states of OAM light beams. A reflected OAM spectrum including a plurality of OAM light beams associated with the aerosols in the atmosphere may be received, and Doppler frequency shifts caused by reflection off the aerosols in the atmosphere may be measured. Laguerre-Gaussian (LG) modes of the received light beams may be detected and sorted based on the OAM states of the LG modes, and wind turbulence values are predicted by analyzing a difference in the Doppler frequency shifts for the received OAM light beams.
