AORC atmospheric forcing data across CAMELS US basins, 1980 - 2024

These data are atmospheric forcings from NOAA's Analysis of Record for Calibration (AORC 2024) summarized over the CAMELS catchments (Addor et al. 2017), however, the delineations over those CAMELS basins were updated by Andy Wood (2024) using the basin boundaries produced for the USGS GagesII effort (Falcone 2011).

Data collected using this repository code: https://github.com/jmframe/CIROH_DL_NextGen/tree/main/forcing_prep, which should be somewhat derivative of this: https://github.com/CIROH-UA/ngen-datastream/tree/main/forcingprocessor.

There are eight variables representing the meteorological conditions:
Total Precipitaion (APCP_surface) - Hourly total precipitation (kgm-2 or mm) for Calibration (AORC) dataset
Air Temperature (TMP_2maboveground) - Temperature (at 2 m above-ground-level (AGL)) (K)
Specific Humidity (SPFH_2maboveground) - Specific humidity (at 2 m AGL) (g g-1)
Downward Long-Wave Radiation Flux (DLWRF_surface) - longwave (infrared) radiation flux (at the surface) (W m-2)
Downward Short-Wave Radiation Flux (DSWRF_surface) - Downward shortwave (solar) radiation flux (at the surface) (W m-2)
Pressure (PRES_surface) - Air pressure (at the surface) (Pa)
U-Component of Wind (UGRD_10maboveground) - (west-east) - components of the wind (at 10 m AGL) (m s-1)
V-Component of Wind (VGRD_10maboveground) - (south-north) - components of the wind (at 10 m AGL) (m s-1)

The data include a timestamp from Coordinated Universal Time (UTC; AORC 2021).

本数据集汇集了来自美国国家海洋和大气管理局（NOAA）历史分析记录校准（AORC 2024）的气象强迫因子，经CAMELS流域（Addor et al. 2017）综合概化，然而，这些CAMELS流域的划分已由Andy Wood（2024）根据美国地质调查局GagesII项目（Falcone 2011）所生成的流域边界进行更新。数据收集遵循本代码库：https://github.com/jmframe/CIROH_DL_NextGen/tree/main/forcing_prep，该代码库与以下代码库具有一定的衍生关系：https://github.com/CIROH-UA/ngen-datastream/tree/main/forcingprocessor。数据集包含八个表示气象条件的变量：
- 总降水量（APCP_surface）：用于校准（AORC）数据集的小时总降水量（kg m-2 或 mm）；
- 空气温度（TMP_2maboveground）：地面以上2米处的温度（K）；
- 特定湿度（SPFH_2maboveground）：地面以上2米处的特定湿度（g g-1）；
- 向下长波辐射通量（DLWRF_surface）：地表的长波（红外）辐射通量（W m-2）；
- 向下短波辐射通量（DSWRF_surface）：地表的向下短波（太阳）辐射通量（W m-2）；
- 压力（PRES_surface）：地表的大气压力（Pa）；
- 风速U分量（UGRD_10maboveground）：西-东方向的风速分量（地面以上10 m）（m s-1）；
- 风速V分量（VGRD_10maboveground）：南-北方向的风速分量（地面以上10 m）（m s-1）。数据包含协调世界时（UTC；AORC 2021）的时间戳。
