I have temperature data from a weather station, but there are missing data (not more than 80% of the daily temperature observations). The World Meteorological Organization has some rules to validate estimations of monthly temperatures, etc. (for example to have 80% of the data). But since my periods of time are related to the lifecycle of the migratory species I am studying, for example: 1) arrival to the breeding ground and egg laying is from 20-May to 20-Jun (31 days) 2) incubation is from 21-Jun to 15 July (24 days) 3) brood rearing is from 16-July to 15-Aug (30 days)
Do you know if there are some other rules? for example when my period of time is <30 days? Does the same rule would apply for the incubation period, even if it is shorter than one month?
thanks a lot for your advice/suggestions
