Данные метеокомпании IBM, максимальная температура и минимальная температура для дневной и ночной части прогноза

В случае прогноза IBM Weather Company Data, какой ключ дает максимальную и минимальную температуру для дневной и ночной части прогноза? В настоящее время я использую:

nightHigh = result.forecasts[0].night.hi;
nightLow = result.forecasts[0].night.wc;

Вот JSON, полученный от вызова API.
