Abstract. Distributed temperature sensing (DTS) is a fiber-optical method enabling simultaneous temperature measurements over long distances. Electrical resistance heating of the metallic components of the fiber-optic cable provides information on the thermal characteristics of the cable's environment, providing valuable insight into processes occurring in the surrounding medium, such as groundwater–surface water interactions, dam stability or soil moisture. Until now, heated applications required direct handling of the DTS instrument by a researcher, rendering long-term investigations in remote areas impractical due to the often difficult and time-consuming access to the field site. Remote control and automation of the DTS instrument and heating processes, however, resolve the issue with difficult access. The data can also be remotely accessed and stored on a central database. The power supply can be grid independent, although significant infrastructure investment is required here due to high power consumption during heated applications. Solar energy must be sufficient even in worst case scenarios, e.g. during long periods of intense cloud cover, to prevent system failure due to energy shortage. In combination with storage batteries and a low heating frequency, e.g. once per day or once per week (depending on the season and the solar radiation on site), issues of high power consumption may be resolved. Safety regulations dictate adequate shielding and ground-fault protection, to safeguard animals and humans from electricity and laser sources. In this paper the autonomous DTS system is presented to allow research with heated applications of DTS in remote areas for long-term investigations of temperature distributions in the environment.

Soil Moisture Monitoring

<p>The hydrologic cycle is currently being altered due to climate change and the potential impacts are diverse. Long-term monitoring of the components of this cycle will aid our understanding of these changes. Soil moisture is one of the components often neglected, with few long-term datasets available. It is an important variable, regulating the exchange of water and heat energy between the land surface and the atmosphere through evaporation and plant transpiration. Our understanding of soil moisture dynamics is often limited, and an expansion of the current monitoring network holds many benefits. Recently, a process was initiated to establish an effective Irish National Soil Moisture Monitoring Network. This network aims to be research question driven, consistent in its measurement approach and designed to be useful for ongoing research. Here we report on the consultation process that started in early 2020 within the Irish Agmet group, a working group on Agrometeorology. Specifically, we (1) provide background to the consultation process that showed widespread support for a long-term soil moisture monitoring network which led to funding applications to establish this network, (2) review initiatives underway to monitor soil moisture and other components of the hydrologic cycle and highlight the benefits of long-term widespread measurements to various initiatives and sectors, (3) suggest new and novel monitoring technologies that will be investigated and (4) provide an implementation strategy for what is anticipated to be an efficient and successful network. The paper should serve as a starting point to obtaining widespread support for a national hydro-climate monitoring network.</p>
