The ASTER Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation model (DEM) of land areas on Earth at a spatial resolution of 1 arc second (approximately 30 meter horizontal posting at the equator).
The development of the ASTER GDEM data products is a collaborative effort between National Aeronautics and Space Administration (NASA) and Japan’s Ministry of Economy, Trade, and Industry (METI). The ASTER GDEM data products are created by the Sensor Information Laboratory Corporation (SILC) in Tokyo.
SENTINEL-2 is a wide-swath, high-resolution, multi-spectral imaging mission, supporting Copernicus Land Monitoring studies, including the monitoring of vegetation, soil and water cover, as well as observation of inland waterways and coastal areas.
The SENTINEL-2 Multispectral Instrument (MSI) samples 13 spectral bands: four bands at 10 metres, six bands at 20 metres and three bands at 60 metres spatial resolution.
Atlas of Living Australia data on invasive alien species in Tuvalu
Data submitted to the UN Ozone Secretariat highlighting the trend of ODS consumption (calculated as Production (if any) + imports - exports) in Tuvalu. Ozone Depleting Substances calculated here are HCFCs and Methal Bromide.
time series data on the consumption of CFC 12 & CFC 115 in Tuvalu in the past and submitted to Ozone Secretariat. This data was reported in the National Compliance Action Strategy to implement the Montreal Protocol on Substances that Deplete the Ozone Layer in Tuvalu

Atlas of Living Australia data on invasive alien species found in Tuvalu
The overall generation rates of 2,904 kg/day is higher than found in the 2017 Tuvalu waste survey (Sagapolutele & Binney, 2017), which provided an estimate of 2,478 kg/day.

By volume from DWM data, 38% of incoming waste is from households and 62% from other sources, including green waste. Landfill sample, gained over 6 days featured much less construction waste than DWM data, given the shorter timeframe and put the ratio at 53% household and 47% other sources.

Greenhouse Gas Emission - Of the total 2014 emissions of 18.467 Gg CO2-e, 11.214 Gg (61%) can be attributed to the energy sector. The main GHGs emitted by Tuvalu are CO2 (60.4% of total emissions), CH4 (16.4%), and N2O (23.1%)
Trends in ODS Consumption - As a developing country, Tuvalu is listed under Article 5 of the Montreal Protocol, and therefore provided with assistance to phase-out consumption of CFCs by 2010, HCFCs by 2030, and HFCs by 2024.
This dataset contains mapping information (shapefile) of reefs in Tuvalu including its distribution. A foundation baseline map for future, more detailed, work.
