1 | Start_day | The number of the first day for which the 10-day cumulative temperature sum of the smoothed temperature exceeds 50°C |
2 | End_day | The number of the first day of the last 10-day cumulative temperature sum of smoothed temperature which exceeds 50°C in the year |
3 | Duration | The number of days for which the 10-day smoothed temperature sum exceeds 50°C (End_day - Start_day + 1) |
4 | Max_day | Day of the maximum value of the smoothed temperature |
5 | Max_temp | The temperature (°C) of the Max_day |
6 | Season_sum | Temperature sum of the smoothed temperature (day degrees above 5°C) during the growing season. |
7 | Spring_sum | Temperature sum of the smoothed temperature (day degrees above 5°C) up to the summer solstice (22nd June). |
8 | Warming_rate | Rate of early season temperature increase from Start_day to Max_day |
9 | Sun_hours | Cumulative sunshine hours for the growing season (calculated for Abisco station, Sweden only) |
10 | Sum_precip | Precipitation sum during the growing season ( Start_day to End_day). |
11 | Degree_day | The number of days in the growing season for which daily-mean temperature exceeds 5°C |
12 | Frost_day | The number of days in the growing season for which daily-minimum temperature is less than 2°C |
13 | Hot_days | The number of days in the growing season for which daily-maximum temperature exceeds 20°C |
14 | Temp_mean | The average of daily-mean temperature obtained for degree days during the growing season |
15 | Temp_min | The average of daily-minimum temperature for frost days i.e. < 2°C during the growing season. |
16 | Temp_max | The average of daily-maximum temperature for hottest days i.e. > 20°C during the growing season |
