RAWS stations are the primary source of near-real-time data within 40 km of LAVO. Sixteen RAWS stations were identified; 13 of these are active (Table 4.3). The only RAWS stations with unreliable data records are “LN2-Portable” and “LN3-Portable,” both located 16 km east of LAVO (Figure 4.1). Most of the 16 RAWS stations have occasional, small data gaps. The most complete data records come from the stations “Carpenter Ridge” (2000-present), 40 km south of LAVO, and “Whitmore” (1990-present), 29 km northwest of LAVO.
One weather station was identified within the boundaries of ORCA (Table 4.3; Figure 4.1). This is a CWOP station (CW2072 Oregon Caves) that provides near-real-time data.
Out of the 23 COOP stations identified within 40 km of the boundaries of ORCA, 13 are active (Table 4.3). The closest COOP station to ORCA is “Bolan Peak,” which is 8 km southwest of ORCA and has been active since 1953. The longest record we identified was from the COOP station “Williams 1 NW,” which is 17 km northeast of ORCA and has been active since 1892. This is a precipitation-only site whose data record is very complete. Another reliable long-term record was identified at the COOP station “Grants Pass,” which is 37 km north of ORCA and has been active since 1893. The COOP station “Happy Camp R.S.” (1914-present) is 32 km south of ORCA. The data record at this site is fairly complete but there are scattered, small data gaps and there are generally no weekend observations. Three other active COOP stations have data records going back to the 1930s and 1940s. “Elk Valley” is 28 km southwest of ORCA and has been active since 1938. This station’s data record has not been reliable since the 1970s. “Buncom 1 NNE” is 35 km northeast of ORCA and has been active since 1948. This station’s data record is mostly complete except for data gaps in August-October of 1984 and in January-October of 1985. “Star R.S.” is 28 km northeast of ORCA and has been active since 1948. Several other active COOP stations we identified have data records beginning in the 1950s and 1960s.
Five active NRCS-SC sites were identified within 40 km of ORCA (Table 4.3). Most of these are located south and east of the park unit (Figure 4.1). The closest sites to ORCA are “Althouse #2” (8 km south) and “Grayback Peak” (8 km east).
RAWS and SNOTEL stations are the primary source of near-real-time data within 40 km of ORCA (Table 4.3; Figure 4.1). Nine RAWS stations were identified; six of these are active (Table 4.3). The most complete data records come from the stations “Illinois Valley Airport” (1985-present), 21 km west of ORCA, and “Provolt Seed Orchard” (1985-present), 25 km northeast of ORCA. Two SNOTEL stations are located within 40 km of ORCA. “Bigelow Camp” is 4 km southeast of ORCA and “King Mountain” is 17 km southeast of ORCA.
Six weather/climate stations were identified within REDW (Table 4.3). Five of these stations are still active. The longest climate record is at the COOP station “Orick Prairie,” which is in the south-central portion of REDW (Figure 4.1) and has been active since 1937. This climate record is fairly complete, with occasional, small data gaps. The COOP station “Schoolhouse Peak,” located in the southeastern part of REDW, also provides a longer data record, having been active since 1953. The NADP station “Yurok Tribe-Requa” is located just north of the mouth of the Klamath River. Two RAWS stations are currently operating within REDW. “Schoolhouse” is in the southeastern part of REDW and has a very complete data record going back to 2001. “Westside” is in the south-central REDW and has been active since 2004. “Westside” has a data gap from January through March in 2005.
Out of the 31 COOP stations identified within 40 km of the boundaries of REDW, 10 are active (Table 4.3). The COOP station “Eureka,” 34 km south of REDW, has the longest record among these active COOP stations, having been active since 1886. The data record at “Eureka” is very complete. The COOP station “Crescent City,” 6 km west of the north end of REDW, has been active since 1893. The record at this station is largely complete but there were no weekend observations during the 1960s and 1970s. A very reliable long-term record was identified at the COOP station “Orleans,” which is located 33 km east of REDW and has been active since 1903. The COOP station “Elk Valley,” discussed previously, is 36 km northeast of the northern end of REDW. “Gasquet R.S.” is a precipitation-only COOP station that is 10 km east of the northern end of REDW and has a very complete data record (1948-present). The COOP station “Klamath” is just outside of central REDW and has a very reliable data record (1948-present).
