“…In addition, several NWP centres have included O
as a variable in the models because it improves the assimilation of specific channels in the infrared, which are sensitive to O
, temperature, and water vapour, and it allows better accounting of radiative feedback, which improves weather forecasts (Coopmann et al .

1998; Dragani et al ., 2018; Ivanova et al ., 2017; John and Buehler,
