to 30 °C for St. Augustine (Trinidad and Tobago). Rainfall was recorded on less than 19 days during the N2O monitoring period, with the exception of the Trinidad and Tobago site which received 31 days of rainfall (Fig. S1). N2O emission peaks observed in LVC pastures tended to be higher than those in AVC pastures in 5 out of the 7 sites (Fig. 1; Table 2). However, the delayed N2O peaks observed at Rio Grande do Sul (Brazil) were higher in the AVC (59 ± 11 mg N2O-N m−2 day−1) compared to the LVC (45 ± 18 mg N2O-N m−2 day−1) pasture. The level of N2O emissions observed at Balcarce and Manfredi (Argentina) and Taluma (Colombia) sites were lower than 50 mg N2O–N m−2 day−1.
