ALMA WVR phase correction algorithms
The atmospheric inference library, libAIR, authored by Bojan Nikolic, is the main core of our algorithms for the phase correction of ALMA data using water vapour radiometers. You can download libAIR here and you may use the code under the LGPL license.
ALMA Atmospheric Modelling
ATM written by Juan Pardo is a library of routines for modelling the transmission of radiation at cm/mm/sub-mm wavelengths through the Earth's atmosphere, which is being extensively used by the ALMA calibration software. To make ATM easier to use for both our work and the wider community, Bojan Nikolic has re-packaged ATM, under the name AATM (for more information see Bojan's AATM page).
