description: This dataset is associated with Tang, W., Llort, J., Weis, J. <em>et al.</em> Widespread phytoplankton blooms triggered by 2019–2020 Australian wildfires. <em>Nature</em> <strong>597, </strong>370–375 (2021). https://doi.org/10.1038/s41586-021-03805-8. A detailed description of the methods and data analysis can be found in Tang, Llort, Weis et al., 2021. This dataset contains: <strong>Aerosol iron data collected during the 2019-2020 Australian wildfires.xlsx</strong>: Aerosol samples were collected in southern Tasmania, Australia downwind of the 2019-2020 Australian wildfires. Concentrations of total iron, labile iron and levoglucosan in aerosols were measured. <strong>MODIS_AOD_mthly_NDJF_2019_2020.nc</strong>: Global monthly mean Aerosol Optical Depth (AOD) at 550nm for the period of November 2019 to February 2020. Source data from NASA-MODIS. <strong>CAMS_AODbc_sum_2019_2020_PAC.nc</strong>:<strong> </strong>Climatological, observed and anomalous black carbon AOD at 550nm accumulated between December 2019 and February 2020 over the Austro-Pacific sector of the Southern Hemisphere, [75ºE-340ºE,10ºS-70ºS]. Based on the daily-averaged outputs of CAMS atmospheric reanalysis. Contains modified Copernicus Atmosphere Monitoring Service Information [2021]. <strong>CAMS_AODbc_mthly_NDJF_2019_2020_PAC.nc</strong>:<strong> </strong>Monthly maximum black carbon AOD at 550nm and black-carbon wet deposition between November 2019 and February 2020 over the Austro-Pacific sector of the Southern Hemisphere, [75ºE-340ºE,10ºS-70ºS]. Based on the daily-averaged outputs of CAMS atmospheric reanalysis. Contains modified Copernicus Atmosphere Monitoring Service Information [2021] <strong>CAMS_DustBCdepo_sum_2019_2020.nc</strong>: Global dust and black-carbon wet deposition accumulated between December 2019 and February 2020 based on the daily-averaged outputs of CAMS atmospheric reanalysis. Contains modified Copernicus Atmosphere Monitoring Service Information [2021]. <strong>OCCCIv42_chla_DJF_2019_2020_PAC.nc</strong>: Climatological, observed and anomalous Chlorophyll-a averaged between December 2019 and February 2020 over the Austro-Pacific sector of the Southern Hemisphere, [75ºE-340ºE,10ºS-70ºS]. Based on monthly outputs of Ocean Colour – Climate Change Initiative (ESA, Sathyendranath et al, 2020), version 4.2. <strong>OCCCIv42_chla_mthly_NDJF_2019_2020_PAC.nc</strong>: Monthly observed and anomalous Chlorophyll-a between November 2019 and February 2020 over the Austro-Pacific sector of the Southern Hemisphere, [75ºE-340ºE,10ºS-70ºS]. Based on monthly outputs of Ocean Colour – Climate Change Initiative (ESA, Sathyendranath et al, 2020), version 4.2. <strong>Global_net_primary_production.nc</strong>: Average climatological and monthly net primary production rates during the 2019-2020 Australian wildfires estimated by 3 net primary production models. <strong>Global_export_production.nc</strong>: Average climatological and monthly export production rates during the 2019-2020 Australian wildfires estimated by the combination of 3 models of net primary production and 3 models of export ratio.
