ESA Sentinel App for Android and iOS
The Sentinel App is a gateway to knowing the Sentinel satellites. It lets users track the satellites in real-time, discover their key elements, read the latest news and learn more about their products. Users can, among other things, explore detailed 3D models of the satellites, see the last and next time they have been and will be over the user's location, move the satellites to the time of the last data transmission and smoothly move them back to their current location over the 3D globe. Notifications can also be set to be warned when the satellites are flying by. ESA is developing a series of next-generation Earth observation missions, on behalf of the joint ESA/European Commission initiative Copernicus (previously GMES - Global Monitoring for Environment and Security). The goal of the program is to replace current and older Earth observation missions, such as ERS and Envisat, which have reached or are close to reaching the end of their operational life span. This will ensure a continuity of data so that there are no gaps in ongoing studies. Each mission will focus on a different aspect of Earth observation, such as Atmospheric, Oceanic or Land monitoring, and the data will be of use in many applications.

The software Fmask (Function of mask) is used for automated clouds, cloud shadows, and snow masking for Landsat (4, 5, 7, and 8) and Sentinel-2 data.
This package implements the Fmask algorithm as a Python module. It is intended that this can be wrapped in a variety of main programs which can handle the local details of how the image files are named and organised, and is intended to provide maximum flexibility. It should not be tied to expecting the imagery to be layed out in a particular manner. This modular design also simplifies the use of the same core algorithm on either Landsat and Sentinel imagery. The wrapper programs take care of differences in file organisation and metadata formats, while the core algorithm is the same for both
The software called Fmask (Function of mask) is used for automated clouds, cloud shadows, and snow masking for Landsat (4, 5, 7, and 8) and Sentinel-2 data.
This website provides links to standalone versions of the Fmask software for Windows, Linux and Apple iOS. In addition, the algorithm is also provided as Matlab code.

NPL, in collaboration with Brockmann Consult, has delivered the first version of the Radiometric Uncertainty Tool (RUT) for the Sentinel-2 mission. This innovative tool provides uncertainty images associated to the Top-of-Atmosphere reflectance images delivered by the European Space Agency (ESA). The first version of the tool already incorporates the possibility to define a specific coverage factor and select/deselect the contributors through the user interface. The uncertainty estimates are based in an exhaustive radiometric analysis of both the instrument and radiometric processing chain of the Sentinel-2 mission. The combination model is based on the GUM guidelines.
TIMESAT is a software package for analysing time-series of satellite sensor data.
TIMESAT has been developed to investigate the seasonality of satellite time-series data and their relationship with dynamic properties of vegetation, such as phenology and temporal development. The temporal domain holds important information about short- and long-term vegetation changes. TIMESAT was originally intended for handling noisy time-series of AVHRR NDVI data and to extract seasonality information from the data. The program now has the capability to handle different types of remotely sensed time-series , e.g. data from Terra/MODIS at different time resolutions. It has also been tested with eddy covariance data and moisture data, although these applications are not the main target.
