Gravity wave temperature fluctuations acquired by the CRISTA instrument are compared to previous estimates of zonal‐mean gravity wave temperature variance inferred from the LIMS, MLS and GPS/MET satellite instruments during northern winter. Careful attention is paid to the range of vertical wavelengths resolved by each instrument. Good agreement between CRISTA data and previously published results from LIMS, MLS and GPS/MET are found. Key latitudinal features in these variances are consistent with previous findings from ground‐based measurements and some simple models. We conclude that all four satellite instruments provide reliable global data on zonal‐mean gravity wave temperature fluctuations throughout the middle atmosphere.
