Pressure data used in 'Surface-to-space atmospheric waves from Hunga Tonga-Hunga Ha'apai eruption' (Wright et al., 2022)

Pressure data used in 'Surface-to-space atmospheric waves from Hunga Tonga-Hunga Ha’apai eruption'  (Wright et al., 2022). 

Phase speed estimates by station:

Author: Fred Prata, AIRES Pty Ltd

Description: distances, locations, arrival times and phase speed estimates for the Hunga Tonga Lamb wave from pressure stations used in our study.

Pressure time series data (19 stations):

Lauder (1 station):

Author: Dan Smale/NIWA, State Highway 85, Omaku, New Zealand

Description: Data sourced from a CO2 eddy-covariance instrument operated and maintained by NIWA.  Values were provided as an image file of pressure anomaly versus time (NZST) which was digitized at approximately 90 s time resolution and 0.1 hPa.

Mt Eliza / HRO (1 station):

Author: Fred Prata/AIRES Pty Ltd, 116 Humphries Road, Mount Eliza, Vic 3930, Australia

Description: Data derived from an ecowitt weather station (Easyweather-WIFIA 19E) operated and maintained by AIRES Pty Ltd.  The measurements are logged every 5 minutes with a pressure resolution of 0.1 hPa.

Tonga (1 station):

Author: Malo e Leilei Taaniela/Fua'amotu Domestic Airport, Tonga and Shane Cronin/University of Auckland, School of Environment, New Zealand.

Description: Data derived from a barometer operated by the Tongan meteorological office located at Nukualofa port (met.gov.to).  Sampling interval is 1 minute and the pressure resolution is 0.1 hPa

Weatherlink (3 stations):

Author: Fred Prata/AIRES Pty Ltd, 116 Humphries Road, Mount Eliza, Vic 3930, Australia

Description: Data downloaded from http://weatherlink.com The time resolution is 5 minutes for Davis and Boston and 15 minutes for Travis.  The pressure resolution is 0.01 in Hg.

PurpleAir (13 stations):

Description: PNG images of pressure traces from each station: American Samoa, Anchorage, Auckland, Brisbane, Colorado Springs, Concepcion, Glenn Dale, Kahuko, Manhattan Beach, Papeete, Solvang, Sydney, Tokyo. See table, described above, for latitude/longitude of each site.

Other pressure data used in the paper already archived elsewhere, and associated licensing (11 stations):

AIMS (10 stations): https://apps.aims.gov.au/metadata/search?term=Weather%20Stations (CC BY 3.0 AU)

Wegenernet (1 station): https://wegenernet.org/portal/v7.1/2021/1 ("openly available to all and free of charge except for commercial usage")

Not included (6 stations):

Due to licensing terms, we do not include 6 pressure time series obtained from the Australian Bureau of Meteorology in their raw form, specifically those at Mt Isa Aero, Learmonth Airport,  Broome Airport, Alice Springs Airport, Adelaide Airport and Perth Airport. Derived products made from these data are permitted to be shared, and accordingly phase speed estimates from these stations are included in the table described above. A graphical representation of the data from Broome is also included in the scientific paper these data support as Extended Data Figure 1e.
