Data trends at meteoLCD
This page with the 9 year trends will be populated in the coming weeks; the trends, mean and standard deviations are computed from the original data series.
Ground
Ozone [ug/m3] ("bad ozone") mean : 41.13 ug/m3 mean of daily max = 76.5 +/- 38.4 |
|
Air
temperature [°C]
mean : 10.25 °C
|
|
Diurnal
Temperature Range (DTR) [°C] DTR = daytimeMAX-nighttimeMIN daytime = 08:00 - 20:00 UTC DTR mean : 7.81 +/- 4.58 daytimeMAX mean: 14.37 +/- 8.34 trend: +0.15 °C/year nighttimeMIN mean: 6.58 +/- 6.03 trend: +0.03 °C/year If DTR is computed as the difference between the diurnal (i.e. 24 hours) Max and Min the trend is +0.08 °C/year |

Total
Ozone Column [DU] ("good ozone") positive trend + 3 DU/year mean : 323.2 DU stdev : 12.4 DU |

The 1998-1999 data are too unreliable to be retained. For 2000-2006: mean: 10.5 ug/m3 |
|
NO2
concentration in ug/m3
