TLDR
Human coronaviruses can persist on inanimate surfaces like metal, glass or plastic for up to 9 days, but can be efficiently inactivated by surface disinfection procedures with 62–71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute.Citations

The Effects of Temperature and Relative Humidity on the Viability of the SARS Coronavirus
TL;DR: The better stability of SARS coronavirus at low temperature and low humidity environment may facilitate its transmission in community in subtropical area during the spring and in air-conditioned environments, which may explain why some Asian countries in tropical area did not have major community outbreaks of Sars.

Effects of Air Temperature and Relative Humidity on Coronavirus Survival on Surfaces
TL;DR: TGEV and MHV could serve as conservative surrogates for modeling exposure, the risk of transmission, and control measures for pathogenic enveloped viruses, such as SARS-CoV and influenza virus, on health care surfaces.
