list.csv Description of 207,173 locations | Data Dimension: 207,173 (R) × 3 (C) C1: Latitude; C2: Longitude C3: Cluster ID (ranging from 1‒5) as defined in Table 1 | |
AMF_WY/ | Annual maximum series with durations of 24 h, 48 h, and 72 h, driven by different hydrometeorological mechanisms over water years 1951‒2013 (10/1/1950-09/30/2013). The mechanisms include W, P, R, ROS, and M as defined in Table 2. | |
[duration]/ [mechanism].csv e.g., 24 h/W.csv | Data Dimension: 207,173 (R) × 65 (C) C1: Latitude; C2: Longitude C3‒C65 [unit: mm]: Maximum value for each year from 1951–2013 | |
AMF_CY/ | Annual maximum series with durations of 24 h, 48 h, and 72 h, driven by different mechanisms (W, P, R, ROS, and M) over calendar years 1950‒2012. | |
[duration]/ [mechanism].csv e.g., 24 h/W.csv | Data Dimension: 207,173 (R) × 65 (C) C1: Latitude; C2: Longitude C3‒C65 [unit: mm]: Maximum value for each year from 1950–2012 | |
IDF/ | Discrete IDF values, i.e., the magnitude of extreme events with durations of 24 h, 48 h, and 72 h, driven by different hydrometeorological mechanisms (W, P, R, ROS, and M). | |
[duration]/ [mechanism].csv e.g., 24 h/W.csv | Data Dimension: 207,173 (R) × 9 (C) C1: Latitude; C2: Longitude C3‒C9 [unit: mm]: IDF values for the return period of 2, 5, 10, 25, 50, 100, and 500 years. NaN indicates no runoff caused by a given mechanism, such as ROS. | |
IDF_90CI/ | 90% C.I. for IDF values in the IDF/ folder described above | |
[duration]/ [mechanism]_H.csv e.g., 24 h/W_H.csv | Data Dimension: 207,173 (R) × 9 (C) C1: Latitude; C2: Longitude C3‒C9 [unit: mm]: 95% quantile for IDF values with the return period of 2, 5, 10, 25, 50, 100, and 500 years. NaN indicates no runoff event caused by a given mechanism. | |
[duration]/ [mechanism]_L.csv e.g., 24 h/W_L.csv | Data Dimension: 207,173 (R) × 9 (C) C1: Latitude; C2: Longitude C3‒C9 [unit: mm]: 5% quantile for IDF values with the return period of 2, 5, 10, 25, 50, 100, and 500 years. NaN indicates no runoff event caused by a given mechanism. | |
trend/ | Sen’s slope of Mann-Kendall trend in annual maximum series associated with different hydrometeorological mechanisms (W, P, R, ROS, and M) over water years 1951‒2013 | |
[duration]/ [mechanism].csv e.g., 24 h/W.csv | Data Dimension: 207,173 (R) × 3 (C) C1: Latitude; C2: Longitude C3 [unit: mm/year]: Sen’s slope. The value is zero if the trend is not statistically significant. | |
Driver/ | Dominant mechanism of extreme W events with different durations and return periods | |
[duration]/ [return period].csv e.g., 24 h/50 y.csv | Data Dimension: 207,173 (R) × 3 (C) C1: Latitude; C2: Longitude C3: Dominant driver IDs; 1 = rain, 2 = ROS, 3 = melt | |
risk/ | Design risk associated with PREC-IDF estimated 100-year extreme events | |
[duration]_ 100 y.csv e.g., 24 h_100y.csv | Data Dimension: 207,173 (R) × 3 (C) C1: Latitude; C2: Longitude C3 [unit: %]: Bias in 100-year events based on PREC-IDF vs. NG-IDF | |
