<p>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)</p>

<p>Do you know if there are some other rules? for example when my period of time is &lt;30 days? Does the same rule would apply for the incubation period, even if it is shorter than one month? </p>

<p>thanks a lot for your advice/suggestions</p>

Are you missing 80% during your critical periods or missing 20%? Do you have any other stations near-by that you can correlate with and estimate the temperatures for missing days? Are the days missing for long periods or is it just a day here or there? If the missing periods are short you would be justified in interpolating between days on either side. What ever you do to fill in, try to do a sensitivity analysis to see how your assumptions for treating missing data affect the result.

For what it's worth, when I upscale rainfall data from 30 min to daily, I take the average of the available data and multiply it by 48 so I'm essentially filling missing values with the average for the day.

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:

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?
