Multiple hydrometric data sets are generated from monitoring stations across the country. Some are shared sites with NIWA and one or more clients, some are Client only sites, and some are shared between external clients. Data are stored initially in NEON, or in TIDEDA format from telemetry systems and generally archived in Aquarius. Data are multi-year. Kathy Walter is data curator.

Near real time raw precipitation, snow depth and snow water equivalent for 3 sites in New zealand

Data collected for BOPRC in the Rotorua and Waimangu geothermal fields

Continuous monitoring data for flow, turbidity, and nitrate for twelve locations (six constructed wetlands, each with one inflow and one outflow). At each of these twelve locations, discrete samples for water quality analysis will be taken monthly and during 3-5 storm events per year. Monthly and event-based water quality samples will be analysed for TSS, TP, DRP, TN, nitrate-N, ammonium-N, and Escherichia coli. These data will be collected and held in a database (Aquarius) in standard form after being checked for quality assurance.
