Hydrogen delta values in precipitation water (aggregated per location)
These datasets contain the mean and variance of hydrogen delta value from
precipitation water sampled at weather stations between 1953 and 2015 in
Europe (GNIPDataEUagg) and in the entire world
(GNIPDataALLagg). These data have been extracted from the
International Atomic Energy Agency IAEA in Vienna (GNIP Project: Global
Network of Isotopes in Precipitation) and processed by us using the function
prepsources. The data are aggregated per location. We no longer
provide the full non-aggregate GNIP dataset in the package as it is not free
to reuse. You can still download the complete GNIP dataset for free, but you
will have to proceed to a registration process with GNIP and use their
downloading interface WISER
(http://www-naweb.iaea.org/napc/ih/IHS_resources_isohis.html).
The dataframes include many observations on the following variables:
| [, 1] | lat | (numeric) | Latitude coordinate [decimal degrees] |
| [, 2] | long | (numeric) | Longitude coordinate [decimal degrees] |
| [, 3] | elev | (numeric) | Elevation asl [m] |
| [, 4] | source_value | (numeric) | hydrogen delta value [per thousand] |
| [, 5] | year | (numeric) | Year of sampling |
| [, 6] | month | (numeric) | Month of sampling |
| [, 7] | source_ID | (Factor) | The unique identifier of the weather station |
These datasets have been aggregated and can thus be directly used for fitting isoscapes.
If you want to use your own dataset, you must format your data as these datasets.
