This research was supported with funding from the National Science Foundation's Chemical Oceanography Program (OCE‐1536996 and OCE‐1537013). Additional support was provided by NASA through Grants NNX14AM37G and NNX14AF93G.

The data products are calculated partial pressure and air-sea flux of carbon dioxide in the main stem of Chesapeake Bay; the dataset also includes all the inputs to the calculation.

The data were derived from the Chesapeake Bay program's Water Quality Database, United States Geological Survey monitoring data, North American Regional Reanalysis, World Data Centre for Greenhouse Gases, and 2016-2018 carbonate system measurements the Chesapeake (Shadwick et al., 2019). See Related Datasets section.

The data are in the form of seven netCDF files:

1. results-pco2-gasex.nc: calculated monthly pCO2 and air-sea CO2 flux in the Chesapeake Bay mainstem, separated into 8 segments and for the total bay (point estimates and Monte Carlo ensembles).
2. atmosph-apres-wspd2_xco2.nc: atmospheric data (squared wind speed, atmospheric pressure, and CO2 mole fraction) used as inputs to the CO2 flux calculation; also provided are intermediate calculation results (airpCO2, CO2 solubility, and gas transfer velocity).
3. nontidal-susquehanna-alk-dic: alkalinity and DIC at the non-tidal station in the Susquehanna River at Conowingo, Maryland (USGS gauge number 01578310).
4. tidal-33stations-database.nc: measured (Chesapeake Bay Program) and calculated variables at the 33 tidal stations in the Chesapeake Bay mainstem (temperature, salinity, oxygen, pH and alkalinity); at the surface- and at the native time resolution of the Chesapeake Bay Program.
5. shadwick2019a-buoy-pco2.nc: hourly pCO2 calculated from the high-frequency measurements of temperature, salinity, and pH at the York River buoy (Shadwick et al. 2019a).
6. shadwick2019b-cruises-alk-dic.nc: surface alkalinity and DIC measurements from 2016-2018 cruises in the Chesapeake Bay mainstem (Shadwick et al. 2019b).
7. cbp-cruises-alk.nc: surface alkalinity measurements from 1986-1991 cruises in the Chesapeake Bay mainstem (Chesapeake Bay Program)
