jason3

A dataset containing lightly preprocessed windspeed values
from the Jason-3 satellite. Observations near clouds and ice
have been removed, and the data have been aggregated 
(averaged) over 10 second intervals. Jason-3 reports
windspeeds over the ocean only. The data are from a six
day period between August 4 and 9 of 2016.

datasets

Functions for fitting and doing predictions with
Gaussian process models using Vecchia's (1988) approximation.
Package also includes functions for reordering input locations,
finding ordered nearest neighbors (with help from 'FNN' package),
grouping operations, and conditional simulations.
Covariance functions for spatial and spatial-temporal data
on Euclidean domains and spheres are provided. The original
approximation is due to Vecchia (1988)
<http://www.jstor.org/stable/2345768>, and the reordering and
grouping methods are from Guinness (2018)
<doi:10.1080/00401706.2018.1437476>.
Model fitting employs a Fisher scoring algorithm described
in Guinness (2019) <doi:10.48550/arXiv.1905.08374>.
