To provide reliable time series of evapotranspiration, we evaluated the performances of four different gap-filling methods when tailored to conditions of hilly crop fields. The tailoring consisted of splitting the time series beforehand on the basis of upslope and downslope winds. The obtained accuracies on evapotranspiration after gap filling were comparable to those previously reported over flat and mountainous terrains, and they were better with the most widely used gap-filling method.

The authors have successfully recommissioned an unused tri-axial Helmholtz coil system. The system now serves as a national facility for calibrating magnetometers. Hide

The presence of magnetic fields in space dominate the way planets interact with different types of plasmas. Thus, measuring them is extremely important when studying space. We present an instrument capable of measuring magnetic fields at a fraction of the cost, power and size of traditional magnetometers. With this technology, a science-grade magnetometer for small satellites can be achieved, enabling the study of the space environment with large clusters of sensors in future missions. Hide

The paper presents the first results of ground penetrating radar investigation in the church in Kłodzko, Poland. The research was part of SEG Field Camp, which was organized by SEG Student Chapter Cracow and SEG Bucharest Student Chapter. The aim was to verify the presence of possible underground structures. Among the most important discoveries are previously unknown crypts. Results of the research might be helpful for future archeological excavations and other investigations in the church. Hide

Based on the morphological characteristics of the four dayside auroral types on images at the Chinese Arctic Yellow River Station (YRS), and by extracting the local binary pattern features and using k-nearest classifier, we make an automatic classification to the auroral images of the YRS and the South Pole Station and obtain the occurrence distribution of the dayside aurora morphology. The results indicate that these auroral types present similar occurrence distributions in the two stations. Hide
