Climatological annual cycle of meteorological parameters in Tokyo, Japan. Daily maximum (max.) and minimum (min.) outdoor temperatures (temp.), precipitation, humidity, sunshine duration, atmospheric pressure, and diurnal range of outdoor temperature for 11 years (2010–2020) were obtained from the climate databases constructed by the JMA and NARO. Sunrise time and sunset time for 7 years (2012–2020) were obtained from the database constructed by the NAOJ to calculate daytime length. Diurnal temperature fluctuation was calculated as differences between maximum and minimum temperature and between maximum and mean temperature. For all meteorological parameters, 11-day moving average was calculated for each calendar day. Data are mean ± s.e.m., n = 11 except daytime length (n = 9).
