| Parameters- what is measured |
|
| Parameters- what is calculated |
|
| Methods used to measure parameters | Measurements are taken at many different spectral intervals from satellite images from NOAA,GMS and Seastar satellites. There are a variety of transformations on the data. |
| Scale of use. | Horizontal:1-50km for satellite and radar |
| Number of records | Radar/GMS/NOAA: 4 terabytes since 1993 includes 200 GB for SST data at 1km resolution. Data for radar/GMS/NOAA comes in at 6GB/day. |
| GIS compatibility. | STT data and atmospheric emission data is geographically located. There may be too much data to use in GIS. |
| Available formats for users. | Multiple proprietry formats. Published papers |
| Access constraints. | 100% NIWA owned |
| Measurement Accuracy | To be completed by database manager. |
| Completeness of dataset | To be completed by database manager. |
| Positional accuracy | To be completed by database manager. |

What are the Current and Emerging Uses of the Database for: |
|
|---|---|
| Assisting with determining historic state/baseline. | This can be done where data sets exist. There is international data dating back to 1982 but it has a lower spatial resolution and accuracy than present day data. |
| Assisting with determining current state/baseline. | The data is used for this. |
| Assisting with modeling possible future outcomes. | This is possible for SST for several months and for weather predictions for 6-36 hours |
| Risk assessment. | This is possible for weather, especially atmospheric microwave and infrared emissions |
| Monitoring site selection and sample design. | This is possible. |
| Aggregating and reporting data locally, regionally or nationally. | The data can be aggregated in different ways depending on purpose. |
