The average monthly mean variation of slant ozone (Z) and UVB transmission (KtUVB) at the present work are found.
The results show: (1) The annual mean SWS declined at a rate of −0.15 m s−1 decade−1, meanwhile, the monthly mean variation of probabilities for six wind ranges showed a bimodal fluctuation.
Monthly mean diurnal variations were calculated for every month of the interval so as to estimate month-to-month variability.

In order to validate the IRI 2012 model for the Singapore region, we used the diurnal variation monthly mean GPS-TEC data for the year 2010 to 2011.
Although the highest monthly mean water temperatures outside embayments on the temperate Pacific Coast are typically much lower than this, regional climatic variation produces monthly mean water temperatures in excess of 21°C in some parts of both San Francisco and Anaheim Bays.
