Downscaled data - currently K. Hayhoe ARRM method based data set.

- Indices (derivative data) – days with temperatures below /above a threshold

- days with precipitation above/below a threshold

- the indices provided by the Natinal Climate Assessment

- Approx. 12km

- Annual indices

- CONUS and Alaska

- K. Hayhoe ARRM downscaled data set – A1b, B1, A2, A1FI

PCM, CCSM3, GFDL 2.1, HadCM3 models

Choices of:
- Index
- SRES scenario
- Threshold
- Map – draw bounding (rectangular) box or enter coordinates, or choose a predefined region
- Time series plot for a period
- Get data
- can view annual maps of index for a model and a given emissions scenario
- time series plot of an index for a period
- extract indices for a future period for a region, model and SRES scenario
