Description

1

Intensively Monitored

Annually monitored site that is selected for intensive monitoring. They are sampled with multiple monitoring visits per year and multiple parameter data loggers. Subset of annually monitored sites.

2

Annually Monitored

Easily accessible site that is monitored every year. Annual monitoring should increase sensitivity to trends, but because these sites are not part of a probabilistic sample, those trends can't be extrapolated to unsampled sites. Small set of sites.

3

Rotating Synoptic

Remote site that is revisited every 10 years and selected using the GRTS (Generalized Random Tessellation Stratified) algorithm. Because they were selected probabilistically, results from these sites can be extrapolated to unsampled sites, but because they are only sampled infrequently, there will be less sensitivity to trends at each site. Large set of sites with only a few visited per year.

4

Synoptic

Remote site that is revisited irregularly/as needed
