Paper Abstract
Since February 2005, an Infrared Radiometer for Millimeter Astronomy (IRMA) has been measuring precipitable
water vapour levels in Chile at the Gemini South site on Cerro Pachon with a second unit added at the Las
Campanas observatories site in August 2005. We have also started data collection with three additional IRMA
units at three locations for the TMT site testing effort. After a number of technical modifications to ensure
reliable operations at much lower sites than IRMA was designed for, 6 months of near continuous pwv data have
been collected at both existing telescope sites and several months of data at TMT candidate locations. These
data are enabling us to compare the sites on diurnal as well as seasonal timescales.
