HavoNet

Two field sites are located within Hawai‘i Volcanoes National Park (HavoNet) representing native forest and a forest invaded by an alien tree species, both within the cloud zone on the …

CraterNet

CraterNet consists of 13 weather stations located in Haleakalā crater (a large erosional depression near the summit) as part of an effort to monitor endemic plant and insect species at …

The Hawai’i Permanent Plot Network

The Hawai’i Permanent Plot Network (HIPPNET) was initiated in 2007 by faculty and research ecologists at the University of Hawaii, USDA Forest Service, and UCLA to investigate forest dynamics across …

Disturbance Driven Rainfall on O‘ahu

This research explores the relationship between 4-types of atmospheric disturbances and their contributions to daily rainfall on O‘ahu Hawai‘i. On average, atmospheric disturbances account for 29% of the annual and 41% of the seasonal (Nov – April) rainfall on O‘ahu Hawai‘i. Cold, fronts are the most common disturbance type, and fronts that cross over the island are shown to bring significantly more rainfall than the fronts that track to the north of the Island chain…

Haleakalā Climate Network

The Haleakalā Climate Network consists of two transects of climate stations along the leeward and windward slopes of Haleakalā Volcano, Maui Island, Hawai‘i. The upper elevation stations are within Haleakalā National Park. HaleNet was established in 1988-90 on the relatively dry west-northwest facing (leeward) slope. The first stations were established in June 1988 at elevations of 960, 1640, and 2120 m…

Using Statistics to Select Atmospheric Predictor Variables

An exploratory analysis found that atmospheric predictor variables selected through statistical methods can lead to more accurate rainfall projections when compared to the previous predictor set used in statistical downscaling for rainfall projections in Hawaiʻi. This figure shows the skill of a linear model in projecting rainfall…
