<abstract>
<p>We present a novel approach based on leveraging a network-wide parameterisation to derive snow water equivalent (SWE) with cosmic ray neutron sensing (CRNS) probes. The network comprises 26 sites (1422&amp;ndash;2901 m asl) in the Italian Alps. The parameterisation was defined by fitting neutron counts to 35 SWE measurements taken at 6 sites in the first half of the 2023&amp;ndash;2024 snow season and validated with 111 SWE data from 2023&amp;ndash;2024 and 2024&amp;ndash;2025 at 13 sites. Our analysis shows that this approach retains good representativeness of the snowpack, which can be extended to unmonitored sites if they have monitored counterparts at similar elevation. This finding overcomes the need for year-round accessibility and increases the number of potential sites for continuous SWE retrieval.</p>
