A myatmo update for iOS 16, which among other things fixes display problems, has been submitted to Apple for review and will be available as soon as possible! Please refrain from contacting us about this. Once Apple has reviewed the update, it will be available on the App Store.
Please note that both the cold sum diagram and the grassland temperature sum diagram are only available for Central European latitudes and cannot be generated for netatmo weather stations that are located outside Central Europe.
Definition of the DWD (Deutscher Wetterdienst): "The cold sum is the sum of the amounts of the negative daily mean values of the air temperature over a certain period of time. It is given without a unit. The cold sum is used to evaluate the thermal conditions (cold) of a winter and is therefore included in the Rule given for the entire winter. " In myatmo, the period from the beginning of January to the end of March is considered.
The following markings apply to the cold of winter:
Grassland temperature sum:
Definition Wikipedia: "The grassland temperature sum (GTS) is a special form of the growth degree days that is used in agro-meteorology. It is used in Central Europe to determine the date for starting field work after winter. A heat sum is generally a certain air temperature Days summed up over the days of a period. The cumulative corrected GTS is used in particular, which is weighted by month: From the beginning of the year, all positive daily averages are recorded. In January it is multiplied by a factor of 0.5, in February by a factor of 0.75, and from March then the “full” daily value (multiplied by factor 1) is included in the calculation. If the sum of 200 is exceeded in spring, the sustainable beginning of vegetation is reached. The background is the nitrogen uptake and processing of the soil, which depends on this temperature sum."
