#SoilOrganicCarbon (organic matter / plant and animal residues at various stages of decomposition) is one of the key indicators of hashtag#soilhealth / soil ecosystem services. But how do you measure and report SOC? We advocate that SOC density [kg/m3] is the central variable to monitor SOC dynamics. It is derived by measuring SOC content and Bulk density (separately) and then by a simple formula:
SOC [kg/m3] = SOC [dg/kg]/100 * BD [kg/m3] * (1-CF)
*CF is the coarse fragments fraction (0-1).

I made a time-series of global annual cropland fractions (0-100%) for 2000 to 2022 based on the GLAD cropland product (https://glad.umd.edu/dataset/croplands). You can download the data from here: https://zenodo.org/doi/10.5281/zenodo.12527545
I prepared data in 4 spatial resolutions: 30-m, 100-m, 250-m and 1km (the 100-m and 30-m resolution data does not fit Zenodo, so you need to used links provided). Total size of this data is about 120GB. I've run all processing using GDAL and terra pkg in R. #OpenEarthMonitor #OpenData

I've created the annual mean, max and standard deviation for (1) bare soil fraction, and (2) photosynthetic and (3) non-photosynthetic vegetation annual at 500 m resolution for 2001–2023 (the original data source is explained in Hill and Guerschman, 2022 / MCD43A4 product). You can access the data from: https://zenodo.org/doi/10.5281/zenodo.11961219

Are you looking for #OpenScience global environmental data sets to use for modeling or decision making? We are putting terrabytes of global COGs on https://OpenLandMap.org, part of our Horizon Europe #OpenEarthMonitor project and with many thanks to @gilabrs and colleagues from the OEMC project. To download data or analyze smaller parts in #qgis please use the oemc QGIS plugin (all explained in the GIF below). Let us know if you have problems accessing the data or ideas what we could add next!

So proud of Julia @opengeohub and the #OpenEarthMonitor project in general for delivering cca. 1.4TB ARCO (analysis-ready cloud-optimized) #OpenData + models and trend-analysis all explained in @PeerJ paper:
"FAPAR monthly time-series at 250 m spatial resolution for 2000-2021"
https://peerj.com/articles/16972/
We specifically looked at differences between potential FAPAR and trends in FAPAR over the last 22 years. The gaps we estimated could help environmental agencies assess land degradation. -
7 exciting keynotes and more to come for the Global Workshop #OpenEarthMonitor 2024 hosted by International Institute for Applied Systems Analysis (IIASA) 2-4 October at Laxenburg, Austria; https://earthmonitor.org/global-workshop-2024/
Please note the deadline to submit abstracts is due: 15th of March 2024! #opendata #earthobservation #datacubes
As all previous global workshops, talks will be video-recorded and shared via https://earthmonitor.org/knowledge-hub/

We have started reviewing all global environmental (published as open) data sets all at one place: https://openlandmap.github.io/book/compendium-of-global-gridded-environmental-data-sets.html
If you are aware of some relevant open global data set that we have maybe missed, please post here, or edit the document directly via Github. Thank you! #opendata #OpenEarthMonitor #OpenLandMap

Dataset 📊| Monthly Aggregated Water Vapor MODIS MCD19A2 (1 km). We just published this complete dataset with long-term global coverage spanning 23 years (2000-2022).
💧 Some of its potential uses include studies in #waterresources, #agriculturalplanning, and #climateadaptation, essential for research institutions, environmental and water resource management authorities. To download this dataset 💦, please visit https://zenodo.org/record/8192544

> a 2013 piece by the remarkable, now 94-year-old Noam Chomsky looking at a future that — from the latest devastating news about #ClimateChange to the revival of #NuclearFears thanks to the war in #Ukraine — is all too of the moment. Of course, Chomsky’s vision of our world was always remarkably ahead of his time
