A New Fully Gap-Free Time Series of Land Surface Temperature from MODIS LST Data

Temperature time series with high spatial and temporal resolutions are important for several applications. The new MODIS Land Surface Temperature (LST) collection 6 provides numerous improvements compared to collection 5. However, being remotely …

How to aggregate daily data into MODIS-like 8 day aggregation pattern?

Several MODIS products come in “8-day” compositions. Suppose we have daily data and we want to aggregate it with this MODIS-like granularity. How can we achieve that? First idea would be to use the great t.rast.aggregate module in GRASS GIS with granularity=“8 days”. But this presents a problem. It does not re-start every year, but aggregates the whole series with 8-day granularity, not considering the year. Meanwhile, MODIS 8-day products re-start the aggregation every January 1st.

Remote Sensing of Phytoplankton Blooms in the Continental Shelf and Shelf-Break of Argentina: Spatio-Temporal Changes and Phenology

We studied the spatio-temporal variations of satellite chlorophyll-a (chl-a) and phytoplankton blooms in the continental shelf and shelf-break of the Argentinean patagonic region by means of an 11-years time series of level 3 (L3) MODIS/Aqua …

Potential of remote sensing to predict species invasions: A modelling perspective

Understanding the causes and effects of species invasions is a priority in ecology and conservation biology. One of the crucial steps in evaluating the impact of invasive species is to map changes in their actual and potential distribution and …

Spatio-temporal variations in chlorophyll-a concentration in the patagonic continental shelf: An example of satellite time series processing with GRASS GIS temporal modules

We studied the spatio-temporal variations of chlorophyll-a concentration and phytoplankton blooms in the continental shelf and shelf break of the Argentinean patagonic region by means of a time series of 11-years of MODIS/Aqua level 3 (L3) …

VARIABLES AMBIENTALES EN LA DINÁMICA ESPACIAL DE OLIGORYZOMYS LONGICAUDATUS (HUÉSPED DEL VIRUS ANDES) EN LA REGIÓN NOROESTE DE CHUBUT, ARGENTINA

Variables ambientales en la dinámica espacial de Oligoryzomys longicaudatus (huésped del virus Andes) en la región Noroeste de Chubut, Argentina

In this thesis work I addressed several aspects of the spatial dynamics of O. longicaudatus, Andes virus and Hantavirus Pulmonary Syndrome (HPS) that contribute to the understanding of the relationships between virus-host-disease system and the …

SOFTWARE DEVELOPMENT FOR THE USE OF SPACE INFORMATION IN SPATIAL AND TEMPORAL SIMULATION OF RODENT POPULATION DYNAMICS

The space technology and the use of space science products offer a vast range of research topics and applications for computer scientists. These research applications are of mandatory interest at the Gulich Institute, a CONAE (Argentine National …
