How did agricultural land use upstream of the Aral Sea change in the last three decades? Here is our new #openaccess paper in @IOPenvironment: “Post-Soviet changes in cropping practices in the irrigated drylands of the Aral Sea basin”: dx.doi.org/10.1088/1748-9… (1/n) 
The study area covers 650 000 km2 of drylands in #CentralAsia, covering #Uzbekistan, #Turkmenistan, and #Tajikistan and including the entire #AmuDarya and parts of the #SyrDarya basins. (2/n)
We computed seasonal spectral temporal metrics from the entire #Landsat archive (1987 to 2019) to produce annual maps of cropping practices using #GoogleEarthEngine #GEE. (3/n)
The best-available-pixel (BAP) tool you have been waiting for! Implemented on #GoogleEarthEngine (#GEE). #Landsat
In #GEEBAP can tune composite parameters, create a #timeseries, set area of interest, AND download surface reflectance outcomes!

Measuring Sky brightness from satellites. Is it possible? Probably!!! It is what our last study says: nature.com/articles/s4159…
I will try to explain it here. Thread👇

This paper has a long story. Everything began 11 years ago, when I was making my PhD. Thesis in Galaxy evolution and @cefalopodo and @peleonk where my PhD. supervisors. at the time, the light pollution was an extreme minority field of research.
We bought some of the very first USB Sky Quality Meters And as I was too busy with my PhD. We discussed that would be very interesting to make a map for the sky brightness distribution around Madrid. So we convinced a student Berenice Pila Diez to start it linkedin.com/in/berenicepil…
