 dom fields are completely characterized by their mean and their covariance
  function. In applications suitable classes of parametrized covariance fun
 ctions are needed. Whilst in the univariate case a large number of classes
  is available\, not that many classes exist in the multivariate case. In t
 his talk we mainly focus on bivariate covariance functions that are genera
 lizations or modifications of models that have been suggested by Tilmann G
 neiting.  In particular\, the univariate cutoff embedding technique is tra
 nsferred to the bivariate case. On that way\, the results for the univaria
 te case had to improved. As examples for the bivariate cutoff technique\, 
 we consider Gneiting's bivariate Matern model and modifications thereof.  
 Finally\, we show that Gneiting's generalized Cauchy model can be combined
  with the fractional Brownian motion to get a parametric model that covers
  both the stationary and the intrinsically stationary case.
