SMOS-Box 2.3 released
This software adds a new processing-tool to the BEAM SMOS-Box that allows for converison of native SMOS data products to NetCDF 4. In addition, the BEAM SMOS Reader Plug-in has been updated to handle SMOS-schemas up to version v05-02-01.
The BEAM team is happy to announce that we have released BEAM 4.11 on June 03rd, 2013.
BEAM 4.11 is shipped with a number of new features, of which the most prominent are:
the Time Series Tool has been included into BEAM, allowing users to create, visualise, inspect, and analyse time series of EO data
the new Temporal Percentile Operator has been introduced; it allows users to perform multiple kinds of gap-filled, spatiotemporal percentile computations.
a dedicated OPeNDAP client which provides an easy interface to arbitrary OPeNDAP servers has been added
NetCDF4 data export, allowing users to write compressed data in HDF5-based NetCDF4 format
Additionally, we have dropped and replaced some outdated parts of BEAM in order to keep it lean. It goes without saying that the new release also encloses a number of bug fixes, which can be inspected at our BEAM issue tracker.
For a complete list of changes please refer to the changelog.
Today we're celebrating the 10th birthday of BEAM! The first version was released on the 6th of December 2002. Since that time, our user community has grown steadily and we have got a lot of valuable contributions and useful feedback that helped us making BEAM what it is today. The BEAM project team is looking forward to continue updating, improving and maintaining the software. Big thanks to ESA and all contributors for supporting BEAM!

BEAM 4.10.3 is now available
On 22 June 2012, we have released BEAM 4.10.3.
The focus of BEAM 4.10.3 lies on fixing several major bugs, for example regarding downwards compatibility when importing pins. Additionally, we made some helpful improvements, such as accuracy enhancement for pixel-based geolocations.
We have introduced a large number of new features; see below for a summary.
BEAM has been greatly enhanced by a number of efficient and user friendly tools supporting validation activities. A number of tools now allow for comparing satellite data with correlative data (e.g. in-situ data or other reference data) imported from external sources. The former statistics tool window has been split into multiple, dedicated tool windows each providing a number of new functions.
Generate (ROI) masks from plots: mark a value range in the plot area (histogram, scatter, profile plots) and create a mask comprising the pixels that fall into that value range. The mask is immediately displayed as an overlay in the satellite image view and can be used as a new region of interest for statistical analyses;
Zoom into plot areas using the mouse wheel;
Axes in plots, if applicable can now use a log10-scaling;
Inspect and export (copy to clipboard) plot data as tabulated data.
Profile plot enhancements
extract satellite data from a transect or track and display it, optionally averaged over an NxN pixel box, optionally filtered by a ROI mask, optionally together with correlative data;
synchronise pixel positions: click the transect graphs in the plot and display a cursor which is shown in both, the plot and also along the track figure shown in the satellite image view.
extract satellite data at geographical points, optionally averaged over an NxN pixel box, optionally filtered by a ROI mask, and display against correlative data fields in a scatter plot;
display regression line and information;
display the 1:1 identity line.
compare two raster datasets and display a density plot of pixel frequencies, optionally filtered by a ROI mask;
quickly invert density colors;
generate histograms of raster data, optionally filtered by a ROI mask;
bin cells of the histogram can now be log10 scaled, thus turning a logarithmic into a normal distribution.
generate common statistical variables, including commonly used percentile thresholds, histogram and percentile plots;
optionally compute statistics for one or multiple masks in one go.
In order to import the correlative data for the new validation tools, support for multiple types of text-based point and vector data sources has been added: plain text, tab-separated CSV files, data extracts from MERMAID in-situ database, and SeaDAS 6.x ship-tracks can now be read and used as vector data within VISAT. All additional columns are kept and, if numerical, may serve as a variable used in the scatter or profile plots.
Double-clicking the imported vector data in the product browser window displays it in a tabular view similar to double-clicking a band which will an image view.
Imported point data can now be interpreted as a path or track and will be displayed accordingly in an image view. Additional numerical columns of such imported point data can be directly displayed in the profile plot.
The VISAT colour manipulation tool window has been enhanced by log10 scaled colour bars.
Three new readers have been added which allow for
reading data products of the new VIIRS (Visible Infrared Imaging Radiometer Suite) instrument. This capability is provided by the SeaDAS Ocean Colour reader which has been developed by the NASA OBPG as part of SeaDAS 7 (http://oceancolor.gsfc.nasa.gov/forum/oceancolor/board_show.pl?bid=28).
reading plain text, CSV files into the BEAM product data model; thus, input from such files may be used for example with the BEAM Graph Processing Tool 'gpt' command-line. Also a corresponding writer is available for CSV.
reading ordinary RGB image files (JPEG, PNG, GIF, ...). Products imported from images comprise the bands red, green, blue with associated wavelength and a grey band which is a linear combination of the three.
The VISAT file import / export menus have been revised due to the meanwhile large number of various data formats BEAM is able to import from and export to.
The following BEAM command-line tool enhancements (see 'gpt -h' on the command-line) have been added
The pixel extraction operator 'PixEx' now uses an extended wildcard syntax to recursively collect source products from a list of directories.
A new operator 'Merge' allows for copying raster data from other data products to a specified 'master' product.
The BEAM Java core data model has been revised: vector data is now based on the OGC-standard for simple features.
Calvalus - An efficient processing system for cal/val and algorithm development is now available
Brockmann Consult successfully completed the ESA Calvalus project - A system which performs efficient bulk processing of large amounts of satellite data. Calvalus aims at supporting Earth Observation cal/val activities and algorithm development by providing fast access to mission-wide satellite data and a highly configurable processing environment. The Calvalus system utilises Apache Hadoop and the ESA BEAM development platform and achieves its enhanced performance from the massive parallelisation and data-local execution of processing tasks.

New MERIS L1 Equalization processor and updates for BEAM 4.8
The MERIS L1 Equalization processor, a new processor for MERIS Level 1 data products, is now available. It performs a radiometric equalization of the MERIS L1b products. It reduces detector-to-detector and camera-to-camera systematic radiometric differences and results into a diminution of the vertical stripping observed on MERIS L1b products.
Additionally, several modules of BEAM have been updated. The changes are listed in the issue summary.

EPR C-API 2.2 released
A maintenance release of Envisat Reader API has been released. The API now functions correctly on 64-bit architectures.
The second version of GlobToolbox is now available for download. It extends the first version of the GlobToolbox by a number of tools tackling the time dimension. First of all, a time series manager allows to define and edit time series. A time series player allows vividly visualising a time series by providing the control elements for navigating through a time series, either manually or automatically. And a time series graph has been developed which may be used to compare values of different measures, such as TSM or SST, for a specified time series.
Apart from time series, the GlobToolbox 2.0 additionally allows to export arbitrary global products to the widely used NetCDF/CF-format.

BEAM 4.8 released
In this release we have added a number of new readers to enable BEAM to work with even more remote sensing products. In particular we have added readers for products originating from the SPOT VEGETATION programme, for Landsat TM products in GeoTIFF format, for HDF-EOS gridded products as well as a reader for generic NetCDF/CF-products. BEAM 4.8 also allows to export products to the widely used data format NetCDF/CF.
As another feature it is now possible to apply "auto-grouping" in the product tree; that is, product nodes whose names begin equally are automatically put into a common group.
Version 4.7.1 of BEAM is a maintenance update. Multiple issues have been addressed to improve the usability of VISAT with the focus on the management of image masks and regions of interest, and their display. It also fixes a number of minor bugs and additionally improves the BEAM Graph Processing Framework (GPF API) in better supporting the development of "window processing" such as image filters and convolutions.
The BEAM CHRIS-Box project has been brought into life in order to support users of data of the CHRIS sensor onboard of the ESA Proba platform. The CHRIS-Box comprises the following add-on modules for BEAM:
The first version of the GlobToolbox is now available for download. It contains multiple data product reader in order to read products the various Glob* projects. Because of that we also call this release the 'Reader Pack'. It does not yet contain tools for generation, inspection and analysis of time series. These fuctionality will be provided with the next releases. If you like, have a look into the GlobToolbox Wiki
