title: Galápagos Archipelago Refined Analysis Validation data

description: This dataset includes (near) surface data variables from the GAR dataset for the model validation period from 2022-04-01 to 2023-03-31.

As this data is part of the GAR dataset, please find additional data at https://data.klima.tu-berlin.de/GAR/

The netCDF format is self-describing, so that all needed metadata are included within the files.

The file names are composed with the following structure:

<model-setup>_<horizontal-resolution>_<time-resolution>_<variable-name>.nc

The shorthands in the file names represent the following:

MM = Name of the model setup, described in Schmidt et al. (unpublished)

d02km = domain with a grid spacing of 2 km

2d = spatial dimensions (2d data, single level)

3d_press = spatial dimensions (3d data, pressure level)

d = time frequency of the data (daily)

m = time frequency of the data (monthly)

y = time frequency of the data (yearly)

psfc = surface (sfc) pressure

q2 = water vapor mixing ratio (qv) st 2 m

q = mixing ratio

prcp = total precipitation (step-wise)

et = actual evapotranspiration (step-wise)

t2 = temperature (temp) at 2 m

theta = potential temperature

sh2 = specific humidity at 2 m

rh2 = relative humidity at 2 m

u10 = 10 m u-wind component

v10 = 10 m v-wind component

ws10 = 10 m wind speed

w = w-wind component

wd10 = 10 m wind direction

hgt = surface height

landmask = landmask

 

The data is in accordance with the CF Conventions CF-1.8
