Abstract Nitrous oxide (N2O) fluxes are influenced by fluctuating soil temperature and external factors such as rainfall events. Therefore, sampling time, frequency of after nitrogen (N) application weather interactions critical when determining cumulative N2O losses associated emission factors. Using automated chambers, three short-term field trials were conducted to measure from urine-affected pasture in southern New Zealand determine the influence light on diurnal variation effect estimated losses. Diurnal flux patterns often interrupted events, but present they mainly driven fluctuations at 0–2 cm depth. Mean daily occurred between 10:00–12:00 h 18:00–21:00 h. Analysis all data, including rainfall-affected periods, showed that gas sample collection times a week provided zero bias calculated emissions compared with those based frequent, 2-hourly, measurements. To account for resource limitations campaigns estimating emissions, an alternative approach is two week, can be expected large (e.g. first 4–6 weeks following urine deposition pasture), additional significant rainfall. This latter produced average +4%, ranged −3 +18%.
