Data on daily average temperature, death rates, and confounding variables (eg, humidity and air pollution) were used to calculate the temperature of minimum mortality (the optimal temperature), and to quantify total deaths due to non-optimal ambient temperature in each location.

The average daily air temperature in the Antarctic summer of 2013, when Goordial collected the permafrost samples which she tested both on the spot and later in the lab, was?

The average daily air temperature in the Antarctic summer of 2013, when Goordial collected the permafrost samples which she tested both on the spot and later in the lab, was − 14 °C and it never rose above 0 °C, making the permafrost difficult to drill.

Linear regression fits to these data were calculated using the R Statistical Software package.22 The data for the San Francisco Bay air basin was queried in a similar manner as above, but instead of recording days above the federal standard the daily average concentrations at the highest monitoring site in the basin are reported by month through October 2017.
