![]() ![]() ![]() The transformations to these climatic data were done to provide users with an intuitive understanding of whether a given month’s total precipitation or average temperature were similar to or different than the corresponding historical average. ![]() Like Alaska, such data limitations required us to constrict our “20th century averages” to the years available. Although data for Honolulu are available from 1890 onward, data for Lihue and Kahului are limited to 1905 forward and Hilo data are limited to 1949 forward, with certain transitory phases during station maintenance also missing data. Hawaii County is represented by the weather station in Hilo, Maui County by Kahului, Honolulu County by Honolulu, and Kauai County by Lihue. These averages are consistent with accepted baseline measures that major governmental and scientific sources use as a point of comparison over long time horizons 2, 3.Īlaska data was limited to 1925 forward therefore our “20th century average” for Alaska is based on the known 75-year time span.įor Hawaiian data, data are limited to a single weather station for each of the state’s four largest counties: Hawaii, Maui, Kauai, and Honolulu. Such methodology was applicable to all counties in the contiguous United States. This provided the average, which was subsequently used to calculate the standard deviation for each county-month pairing. We reconstructed these averages to verify that we were using the proper methodology and then applied that methodology to the county-level monthly average dataset. These averages are specific to each county and month. NCEI references these averages as varieties of climate normals, we will reference these values as average. The NClimDiv database hosts multiple types of historical averages: 30-year averages starting from 1901, 1895-2010 average, and 20th century average, the latter is being used in this experience. Although presented side-by-side with the county-level averages, the Hawaiian data are station-specific averages and should not be considered representative of county-level climate. To provide a comprehensive account of climate across the United States, we supplemented the dataset with individual station data for each county in Hawaii. Those data exclude Hawaii because NCEI indicated county-level averages could not be constructed with the limited data and highly variable climate patterns of the Hawaiian Islands. We leveraged the county-level temperature and precipitation averages to showcase climatic anomalies in comparison to the 20th century average. Its NOAA Monthly US Climate Divisional Database (NClimDiv) 1 provides data for temperature, precipitation, drought indices, and heating and cooling degree days for US climate divisions, states, multi-state regions, and the nation from 1895 to the present. The National Centers for Environmental Information (NCEI), is a sub-bureau of the National Oceanic and Atmospheric Administration (NOAA). ![]() Go down the fireroad and take Sulphur up, turn right at the Helipad, then within 400m is the trailhead with signage.Data Methodology Temperature and Precipitation Datasets Dataset Description Then ride Ridge to the second trail (past Coral). Take the road outside the park to the crest at Eureka Canyon, then ride up Buzzard lagoon into Nisene, and then to Rosalita for the Demo entrance. It was done to reduce getting t-boned on the fire road, but it requires a pedal stroke or four to get off the Braille. A new-ish route at the bottom has you come out parallel to the fire road. Near the bottom is a fat four foot high fatty log with a ramp up and a huck to flat on the other end. As you get closer to the bottom the trail weaves between redwoods and has one G-out that may catch you in the wrong gear forcing you over a skinny a redwood ramp - 3 ft. You can choose one or the other, but hitting both at speed is tough as they are not in line. There is a skinny bridge and a teeter totter about half way down (easy to go-round). The other items you'll find as you descend are steep (steep) scalloped skinny lines over roots. It is easy to skip them and try them at a later date. Inspect them before you try them, as at one time or another they have all been awesome. Looking around as you descend you'll see at least 5 ramp jumps built by trail gnomes. As you enter on a fairly flat sector, you'll do a couple esses and soon come to a log drop of about 3-4 feet, and from there, it gets fun. The trailhead off Ridge Trail has signage to call the top. ![]()
