That paper found both nighttime and daytime temps went up in the absence of contrails, days more than nights. However, the issue isn't settled.

3. Results and discussion
a. Tmax and Tmin spatial trends Although both the 3-day U.S.-averaged Tmax and Tmin were warmer than normal for the grounding period, the Tmin increase (0.38C) was about one-fourth that of Tmax (1.28C). This asymmetric variation from the long-term means may indicate that the lack of contrails impacted the daytime temperatures more than those at night. Such a possibility accords with the observed greater frequencies of contrails during daytime versus nighttime hours, in association with diurnal differences in the frequencies of jet aircraft flights (Bakan et al. 1994; Minnis et al. 1997).
