The SMAP and Copernicus Sentinel 1A/B microwave active-passive high resolution surface soil moisture product
2019
Abstract Soil Moisture Active Passive (SMAP) mission of NASA was launched in January 2015. Currently, SMAP has an L-band radiometer and a defunct L-band radar with a rotating 6-m mesh reflector antenna. On July 7th, 2015, the SMAP radar malfunctioned and became inoperable. Consequently, the production of high-resolution active-passive soil moisture product got hampered, and only ~2.5 months (April 15th, 2015 to July 7th, 2015) of data remain available. Therefore, during the SMAP post-radar phase, many ways were examined to restart the high-resolution soil moisture product generation of the SMAP mission. One of the feasible approaches was to substitute the SMAP radar with other available SAR…
The SMAP mission combined active-passive soil moisture product at 9 km and 3 km spatial resolutions
2018
Abstract The NASA Soil Moisture Active Passive (SMAP) mission was launched on January 31st, 2015. The spacecraft was to provide high-resolution (3 km and 9 km) global soil moisture estimates at regular intervals by combining for the first time L-band radiometer and radar observations. On July 7th, 2015, a component of the SMAP radar failed and the radar ceased operation. However, before this occurred the mission was able to collect and process ~2.5 months of the SMAP high-resolution active-passive soil moisture data (L2SMAP) that coincided with the Northern Hemisphere's vegetation green-up and crop growth season. In this study, we evaluate the SMAP high-resolution soil moisture product deri…
The synergy of water quality and sea surface currents data in determining the spatio-temporal evolution of large-scale circulation features
2014
Chlorophyll-a (CHL-a) and Sea Surface Temperature (SST), amongst others, are proxies or indicators for water quality and can be easily retrieved synoptically and almost in near-real time through satellite remote-sensing. However, as they evolve in space and time in response to winds and currents, a full resolution of the temporal and spatial scales of these latters is required and their influence in shaping the distribution of water quality parameters needs to be assessed. While providing synoptic views and revealing mesoscale features, satellites suffer, indeed, from inadequate representation of sub-grid physical processes and lack of temporal resolution. Conventional point-wise measuremen…
Target Classification by mmWave FMCW Radars Using Machine Learning on Range-Angle Images
2021
In this paper, we present a novel multiclass-target classification method for mmWave frequency modulated continuous wave (FMCW) radar operating in the frequency range of 77 - 81 GHz, based on custom range-angle heatmaps and machine learning tools. The elevation field of view (FoV) is increased by orienting the Radar antennas in elevation. In this orientation, the radar focuses the beam in elevation to improve the elevation FoV. The azimuth FoV is improved by mechanically rotating the Radar horizontally, which has antenna elements oriented in the elevation direction. The data from the Radar measurements obtained by mechanical rotation of the Radar in Azimuth are used to generate a range-angl…

Identifying sedimentary structures and spatial distribution of tsunami deposits with GPR - examples from Spain and Greece
2011
Shallow drilling in coastal areas like southern Spain and different parts of Greece (Corinth region and Argolis Gulf) proved evidence for tsunamis. Sedimentary analyses were conducted to identify tsunamigenic deposits, but did not reveal sedimentary structures or spatial distribution of tsunamites in a regional scale. Since drilling is time-intensive and expensive (depending on extend), this method can by far not cover an entire coastal area. On the other hand, distribution and preservation of tsunamigenic deposits seems to be highly variable. We used ground penetrating radar (GPR) in combination with electrical resistivity tomography (ERT) measurements and sedimentological research methods…
Pedagogu motivēšana sadarbības ieviešanai skolā
2021
Šobrīd Latvijā notiek mācību satura un pieejas pilnveide. Svarīga šajā brīdī ir skolotāju kopīga mācīšanās, lai skolēns veidotu padziļinātu, starpdisciplināru izpratni, pēctecīgi un pamatīgi attīstu savas prasmes. Skolas vadībai nākas domāt, kā organizēt un vadīt skolotāju uz pozitīvu sadarbību ar saviem kolēģiem. Maģistra darba mērķis ir izpētīt pedagogu sadarbības nepieciešamību un motivāciju, lai izstrādātu ieteikumus pedagogu sadarbības veidošanai skolā. Maģistra darba ietvaros X skolā tika veikts gadījuma pētījums. Pētījumā piedalījās 17 pedagogi. Analizējot literatūru par pedagoga lomu skolā un motivāciju sadarboties, veicot pedagogu secināts, ka pedagogu sadarbība var notikt plānošan…
