Second to last @SGC2022 is about to start and I'm excited to say that it is an #EO panel with some folks from @NOAA, moderated by @aravind_raves.
Title is "Utilizing Earth Observations in Addressing Modern Challenges" and livestream is here:

Irene starting us off emphasizing the importance of NOAA satellites in monitoring societal impacts beyond weather: disasters, agriculture, commodities, climate change,
"Key is we have to translate what this actually means to the citizens of the world."

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!

Massive new #QGIS plugin: #GEE Timeseries Explorer offers instant access to #EarthEngine image collections! Fetch #Landsat, #Sentinel2, or #MODIS #timeseries for any location and visualize images: geetimeseriesexplorer.readthedocs.io 🧵
Choose from our predefined collections, for instance merged & #cloud masked #Landsat TM, ETM+, OLI surface reflectance, cloud masked Sentinel2AB L2A, or just define your awesome custom collection in the built-in #Python editor.
Extract time series profiles for #training / #validation by clicking on map, or by navigating through vector point file. Download raw time series data for #sample-based workflows efficiently with parallel download.
