LABOCA sky opacity monitor

LABOCA zenith opacities calculated from a linear combination of the LABOCA skydips results and the opacities determined from the APEX radiometer.
Download all opacities (BoA format) which is generated automatically using a pipeline reduction and it is recommended that users check the entries for the MJDs of the science observations when using this file in the BoA data reduction. Some skydips are still missing in this list, especially in the data from 2007 and 2008. Users are adviced to carefully check if the time range closely samples the time of their observations, as an interpolation over too long a time range may give unreliable opacities. Please also consult the historical weather data here A completed version of this opacity interface will be published soon.
