The Harvard-NUIST Joint Laboratory for Air Quality and Climate (JLAQC) is a collaboration started in August 2017 between Harvard University and Nanjing University for Information Science & Technology (NUIST) to work on atmospheric chemistry and other environmental problems of pressing importance to society, and to contribute to development of the GEOS-Chem atmospheric chemistry model for the benefit of the Asian GEOS-Chem research community. JLAQC offers posdoctoral, exchange, and visiting positions co-hosted by the Harvard School of Engineering & Applied Sciences (SEAS) and from the NUIST School of Environmental Science & Engineering. JLAQC is co-led by Prof. Daniel Jacob (Harvard) and Prof. Hong Liao (NUIST).

JLAQC also hosts regional GEOS-Chem Asia meetings to bring together the atmospheric chemistry research community working with GEOS-Chem. The 1st GEOS-Chem Asia meeting (GCA1) was held at NUIST on May 21-23, 2018. The 2nd GEOS-Chem Asia meeting (GCA2) had to be rescheduled twice because of Covid and is now scheduled for 2025.
