Abstract. The isotopic composition of throughfall is affected by complex exchange, enrichment, and mixing processes in the tree canopy. All interception processes occur simultaneously in space and time generating a complex pattern of throughfall in amount and isotopic composition. This pattern ultimately cascades through the entire hydrologic system and is therefore crucial for studies in catchment hydrology where recharge areas are often forested while reference meteorological stations are generally in the open. For the quasi real-time observation of the isotopic composition of both gross precipitation and throughfall we developed an approach combining an off-the-shelf membrane contactor (Membrana) with a laser-based Cavity Ring-Down Spectrometer (CRDS, Picarro), obtaining isotope readings every two seconds. For the continuous observation of the temporal effect of interception processes two setups with two CRDS instruments in parallel were used analysing gross precipitation and throughfall simultaneously. All devices were kept small to minimize dead volume and thereby, with time-lags of only four minutes, to increase the temporal resolution of isotope observations. Complementarily, meteorological variables were recorded in high temporal resolution at the same location. Comparing these high temporally resolved continuous measurements with discrete liquid or event-based bulk samples, this approach proves to be a powerful tool towards more insight in the very dynamic processes contributing to interception during rainfall events.

Analysis System

The introduction of the virtual instrument technology provides new ideas for the developments of the temperature acquisition. This paper presents the design of temperature acquisition system based on VI technology. This system takes LABVIEW as the software development platform, simulating environmental temperature parameters via temperature sensors and heaters. Through the USB-6009 data collecting cards environmental temperature is sent to LABVIEW software platform for analysis. The system has the functions of data acquisition, display, storage, callback, save, analysis, printing statements and limit alarm processing and so on, and completes the real-time collection and analysis of the temperature.
