Satellite(s)

Many. Global datasets of climate re-analyses, which are partly derived from satellite data.

Monitoring element

Satellite/sensor dependent.

Monitoring element

Satellite/sensor dependent.

Description technique

ERA5 is the fifth generation ECMWF atmospheric reanalysis of the global climate.

Accuracy / Resolution

Resolution is 0.25 arc-degrees (approximately 25km).

Case study

Global climate data is a possible alternative to, or can be used in conjunction with, NZ data (e.g. VCSN).

Also fits domain

Freshwater, Land

Benefits

  • Daily.

  • Data freely available.

Limitations

Steep learning curve for a non-expert, e.g., using the Google Earth Engine requires some investment in time.

Applicability for Northland

Yes.

Ideally it could serve as an interpolator between ground observations. Westerhoff (2015) provide examples of that interpolation.
