Wet tropospheric correction for satellite altimetry using SIRGAS-CON products
Journal of Geodetic Science, 2022 The wet tropospheric correction (WTC) is a required correction to satellite altimetry measurements, mainly due to the atmospheric water vapor delay. On-board microwave radiometers (MWR) provide information for WTC estimation but fail in coastal zones and

Assessment of SIRGAS-CON tropospheric products using ERA5 and IGS
Journal of Geodetic Science, 2022 Zenith Tropospheric Delays (ZTDs) are used to correct tropospheric effects that cause a delay in the signal measured by Global Navigation Satellite Systems (GNSS) receivers and obtain accurate measurements.

Plant Biology, Volume 28, Issue 2, Page 441-451, March 2026.Cave environments filter plant traits, selecting thinner, smaller leaves with reduced photosynthetic and vascular structures. Abstract Caves present unique ecological conditions that influence the distribution and adaptation of species, yet studies on cave‐associated vegetation remain limited.
