Hydrogen delta values in precipitation water (aggregated per location)
Description
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 (across all month-year combinations). 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 (https://nucleus.iaea.org/wiser/index.aspx).
Format
The *dataframe*s include many observations on the following variables:
[, 1] | source_ID | (*factor*) | The unique identifier of the weather station |
[, 2] | mean_source_value | (*numeric*) | Average of the aggregate of hydrogen delta values (per thousand) |
[, 3] | var_source_value | (*numeric*) | Variance of the aggregate of hydrogen delta values (per thousand^2) |
[, 4] | n_source_value | (*numeric*) | Number of hydrogen delta values aggregated |
[, 5] | lat | (*numeric*) | Latitude coordinate (decimal degrees) |
[, 6] | long | (*numeric*) | Longitude coordinate (decimal degrees) |
[, 7] | elev | (*numeric*) | Elevation asl (m) |
Details
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.
