ABSTRACT:

The 10k research plot is located about 250m north of the 10K Trailhead parking lot in the Cibola National Forest. This area is at the beginning of the Canadian/Hudsonian Zone of the Eastern Sandia Mountains, which is part of the Arizona/New Mexico Mountains Ecoregion. The plot is roughly 1,200m^2 and runs east-west with an open area (~400 m^2) on the eastern end and a forest stand (~800 m^2) located uphill on the western end. The hill has an eastern aspect with an 18 degree slope. The forest vegetation in this area predominantly consists of spruce, fir, and aspen trees. Snow depth data was collected manually at this site from February 8, 2019 until May 10, 2019 using a 3-meter snow depth probe.

The hill has an eastern aspect with an 18 degree slope. The forest vegetation in this area predominantly consists of spruce, fir, and aspen trees. Snow pit density, temperature, and stratigraphy data were collected at two snow pits (forested and open areas) from February 8, 2019 until April 12, 2019.

The hill has an eastern aspect with an 18 degree slope. The forest vegetation in this area predominantly consists of spruce, fir, and aspen trees. Liquid water content (LWC) data was collected and estimated using a snow calorimeter (Kasashima et al., 1998) during the spring snowmelt period (February 25, 2020 - April 28, 2020) once the snowpack became isothermal. Two snow pits (open and forested areas) were dug to collect LWC data.

ABSTRACT:

The Navajo River, located in the southern San Juan Mountains, is a tributary of the San Juan Chama River. The Navajo River catchment is one of three catchments included in the San Juan Chama Project (SJCP, Bureau of Reclamation), which diverts water to the Rio Chama via the Azotea tunnel. This system supplies a firm yield (annual allocation) of 96,200 acre-feet to water users in New Mexico. The Oso Diversion, which diverts Navajo River water, contributes about 70% of the project water. To meet the snow monitoring and water supply forecast needs of the SJCP project, a snow survey research area has been established in the catchment. This research area includes four snow survey sites and two weather stations. This site is also used to assess satellite snow measurements to improve snow water supply forecasting for the Snow Water Supply Forecasting Program (Bureau of Reclamation).

To meet the snow monitoring and water supply forecast needs of the SJCP project, a snow survey research area has been established in the catchment. This research area currently includes four snow survey sites, which contain a total of two snow pits and five snow depth transects. Two survey sites include snowtography poles with game cameras monitoring snow depth and temperature buttons collecting snowpack temperature data. During the 2021-2022 winter season, data from three snow depth transects and two snow pits were collected monthly between January and April.

Snow depth retrievals were processed using a retrieval algorithm that utilizes single-look complex (SLC) data from the Sentinel-1 synthetic aperture radar (SAR) satellite and saved in a NetCDF file.
