CCI Land Cover: Prototype high-resolution Land Cover map of Africa released

The first high-resolution (20 m per pixel) land cover map (prototype), classifying land cover types on the entire continent of Africa, has been released by the ESA Climate Change Initiative (CCI) Land Cover project. This is a prototype map, created using a year's worth of data from Sentinel-2a, allows for the exploration of Africa's diverse landscapes in detail. User feedback is requested on the use of the dataset.

The Use of Satellite Data in Ice-sheet Sea-level Projections

The use of satellite data is vital to producing improvements in ice-sheet sea-level projections; a new paper (click here for link, published in Nature Climate Change) by the Antarctic Ice-sheet CCI project science leader, Andrew Shepherd (Centre of Polar Observation and Modelling (CPOM), University of Leeds), explains how ice-sheet models have improved and shows, by comparing Intergovernmental Panel on Climate Change (IPCC) predictions of ice-sheet sea-level rise with Ice-sheet Mass Balance Inter-comparison Exercise (IMBIE) data, that IPCC AR5 projections match actual ice-sheet trends.

RSE Special Issue on EO of ECVs by CCI Scientists

The aim of this special issue (click here for link), published in the Remote Sensing of Environment (RSE) journal, is to demonstrate how Essential Climate Variables (ECVs) can be generated from Earth Observation (EO) data and then used in climate modelling and other climate-related applications. Included in this issue are a number of papers solicited from those involved in running the Climate Change Initiative (CCI) ECV projects as well as the wider community of CCI dataset users.

CCI Soil Moisture Featured in BAMS State of the Climate in 2016 Report

The CCI Soil Moisture project are proud to announce that their overview of recent and historical global soil moisture conditions have been published in the State of the Climate in 2016 Report (released August 2017), the authoritative annual summary of the global climate that is published as a supplement to the Bulletin of the American Meteorological Society (BAMS).

The Calving of Antarctica's Larsen-C Ice Shelf

Last month we witnessed, with the aid of radar satellite Sentinel-1, Larsen-C, the largest remaining ice shelf on the Antarctic Peninsula, calve one of the biggest icebergs on record. Since the breakaway, Dr Anna Hogg (University of Leeds), a CCI Research Fellow working on the CCI’s Antarctic Ice Sheet project, and Dr Hilmar Gudmundsson (the British Antarctic Survey) have continued their research/monitoring efforts with the aim of improving our general understanding (i.e. the mechanics involved) of ice shelf life cycles, where calving events are naturally included and so not necessarily indicative of changing environmental conditions, and their important role in ice sheet stability.

CCI+ Information Day

Following the allocation of new subscriptions to ESA's Climate Change Initiative in December 2016, the Climate Change Initiative programme organised an Information Day to provide potential bidders and stakeholders with information on future procurements under the CCI programme element over the period 2017-2020.

Please note that bidders for projects under CCI+ are limited to the Member State contributing to the programme: AT, BE, CH, DE, DK, ES, FI, FR, GB, IE, IT, LU, NL, NO, PT, RO, SE, CA.

CCI Sea Ice

In this video, the science lead for the CCI project on Sea Ice, Stein Sandven of the Nansen Environmental and Remote Sensing Centre (Norway), provides an introductory explanation of the importance of making global observations on sea ice within the context of improving our understanding of climate change.

This video is featured on the Climate from Space app and can also be found on ESA’s YouTube channel.

New Sea Ice Concentration Climate Data Record by the EUMETSAT OSI SAF

The EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF) recently released a full reprocessing of their Sea Ice Concentration (SIC) Climate Data Record (CDR). Built on the SMMR, SSM/I, and SSMIS series of instruments, it covers years 1979 through 2015. The OSI SAF data record is designed to be compatible with the ESA CCI Sea Ice SIC CDR, which was announced earlier this year. In particular, the two projects shared the same algorithms, processing chains, and file format.

Rapid Changes in Arctic Glaciers

The team of scientists working under the CCI’s Glaciers project have been using radar and optical satellite data to carefully map Earth’s glaciers at different points in time in order to determine changes to their glacial geometries (e.g. extent and elevation) and movements (i.e. speeds) under a changing climate.  For example, and most recently, the observations provided by the Copernicus Sentinel-1 satellites have shown that the Negribreen glacier, sitting on Norway’s Spitsbergen island in the Svalbard archipelago, has experienced a surge in ice surface speed – increasing from 1 to 13 m per day over the winter months of 2016/2017.

Satellite Tracking of Ice Loss in Antarctica

An international team of researchers, led by Dr. Anna Hogg, a CCI Research Fellow working on the CCI’s Antarctic Ice Sheet project, has published the findings of their latest study on glacier flow on the southern Antarctic Peninsula. The study has used over two decades of observations, by five radar satellites (incl. ERS, Envisat and Sentinel-1), to importantly show that the increase in glacier flow (i.e. ice velocity) in this particular region of the world is only a third of what was recently reported. 

The publication in Geophysical Research Letters can be found here. The publication’s lead author, Dr. Anna Hogg from the University of Leeds’ School of Earth and Environment, is part of the UK's Centre for Polar Observation and Modelling (CPOM).
