Data Collections

By default ACE comes with several data collections which can be seen using the Collection Browser.  Here we document where these datasets came from:

Cutoff Rigidity – Korte Constable 2005

We use the supplementary data from Lifton et al. (2008) available from here. A csv file version which can be modified and imported into ACE is available for download: Cutoff Rigidity - Korte Constable 2005.

Geomagnetic Intensity – Channell 2009

Is the geomagnetic paleointensity record from Channell et al (2009), with an additional linear interpolation between 0 and 5 ka to a present day intensity of 7.5 x 1022 Am2 (normalization factor) so that the record begins at the present day.  The original data was obtained from the supplementary section of the online edition. A csv file equivalent of this record is available as: Geomagnetic Intensity - Channell 2009.

Geomagnetic Intensity – Guyodo Valet 1999

Is from a combined record of Yang et al. (2000) up to 12 ka, and then Guyodo and Valet (1999) up to 800 ka. A more accurate title for this record would be ‘Geomagnetic Intensity – Guyodo Valet 1999 + Yang 2000′, but as this record is used in other records to fill in missing data (see below as GV 1999) we used a more compact form. A csv file equivalent of this record is available: Geomagnetic Intensity - Guyodo Valet 1999.

Geomagnetic Intensity – GV 1999 + Yamazaki Oda 2005

Uses intensity values from Guyodo and Valet (1999) up to 8.96 ka, and then uses the paleointensity record of Yamazaki and Oda (2005) up to 2236.3 ka.  Any samples with ages calculated beyond this value use the mean intensity calculated over the entire record. A csv file equivalent of this record is available: Geomagnetic Intensity - GV 1999 + Yamazaki Oda 2005.

Geomagnetic Intensity – Knudsen et al 2008 + GV 1999

Uses intensity values from Knudsen et al (2008) up to 49.5 ka, and then uses the paleointensity record of Guyodo and Valet (1999) up to 300.5 ka.  Any samples with ages calculated beyond this value use the mean intensity calculated over the entire record. A csv file equivalent which can be modified and imported into ACE is available: Geomagnetic Intensity - Knudsen et al 2008 + GV 1999.

Geomagnetic Polarity – Ohno Hamano 1992

Uses polar wander data from Ohno and Hamano 1992 back to 10ka. A csv file of this record is available: Geomagnetic Polarity - Ohno Hamano 1992.

Sea Level – Fairbanks 1989 Shackleton 2000

Uses Fairbanks 1989 eustatic sea level change back to 17 ka then a rescaled Shackleton 2000 reconstruction back to 408 ka. A csv file equivalent which can be modified and imported into ACE is available: Sea Level - Fairbanks 1989 Shackleton 2000.

Sea Level – Lambeck and Chappell 2001 + SPECMAP 1984

Uses Lambeck and Chappell (2001) eustatic sea level back to 21 ka and then a rescaled SPECMAP 1984 stack from Imbrie et al (1984).  A csv file equivalent which can be modified and imported into ACE can be downloaded: Sea Level - Lambeck and Chappell 2001 + SPECMAP 1984.

Sunspot Record – Solanki 2004

Uses the record of Solanki et al. (2004) using a record constructed by Lifton et al. (2005) and available here.  This is to ensure consistency with the original Lifton 2005 scaling. A csv file equivalent which can be modified and imported into ACE is available: Sunspot Record - Solanki 2004.

Obviously some data resampling and splicing has occured in the above datasets.  If you would prefer to use your own datasets these can be easily imported into ACE using the Collection Browser. If you would like to see your (or other, published) data listed for inclusion in ACE please email us.
