Accumulated parameters: accumulated temperature and accumulated precipitation

The Accumulated Parameters include accumulated temperature and accumulated precipitation.

Accumulated temperature is the sum, counted in degrees, by which the actual air temperature rises above or falls below a threshold level during the chosen time period.
Accumulated precipitation is the sum, counted in millimeters, of daily precipitation during the chosen time period.

Accumulated temperature

Call accumulated temperature data by city ID, city name and geo coordinates.

By city name

API call

`end`	required	End date (unix time, UTC time zone), e.g. end=1589445367
`appid`	required	Your unique API key (you can always find it on your account page under the "API key" tab)
`threshold`	optional	All values smaller than indicated value are not taken into account
