Data Handling and Validation Tools
|
|
|
| |
There are a number of tools to help validation data providers. There are summarised in the table below, and include:
| Validation Data |
The NILU Database |
The data coming from the various validation campaigns will be
held within a central storage facility established at the Norwegian
Institute for Air Research (NILU) in Norway. NILU will provide access
to correlative measurements from sensors on-board satellites, aircraft,
balloons and ships as well as from ground-based instruments and under-water
devices and numerical models, such as that of the ECMWF. Users can
connect to the database to add or retrieve data according to their
requirements. All PI's should have their own login name and password, and should
upload data in a specified HDF format as soon as it is available after
validation campaigns. |
| Envisat Data |
ESA User Services Facility |
Post commissioning, the ESA User Services Facility can be used to search and order
ENVISAT data products. Users must register to receive a username and
password, and can then use the facility online.
|
| EnviView |
EnviView is a platform independent software tool
that is capable of reading all ENVISAT products. It includes a basic
'quick-look' visualisation capability and the facility to extract
data, or subsets of data for post-processing. Also included is an
option to convert the data from PDS to HDF 4.1 r2 format, which can
then be read into other software packages, and is useful for comparison
with data held in the NILU database. EnviView
is available on CDROM from ESA or can be downloaded from the Envisat webpages.

Mission planning helpdesk
|
Any problems with ENVISAT data
should be directed to the mission planning helpdesk. This can be reached
at maps@jw.estec.esa.nl |
| CFI software libraries |
The mission CFI software is a collection
of software functions performing accurate computations of mission
related parameters for ENVISAT. These functions are delivered in the
form of software libraries gathering the functions that share similar
functionality. To retrieve them, a registration procedure is necessary. |
| ESOV |
The Earth Map and Swath Visualisation tool (ESOV) is
a collection of software functions that perform accurate computations
of mission related parameters. The use of the software will assist
in planning data acquisition designed to coincide with the overpasses
of ENVISAT and other sensors. The updated orbit for ESOV distributed at launch can be downloaded
here |
| Web Based TIME utilities |
Two time conversion calculators
are available - a basic calculator for any user and an advanced calculator
for users knowledgeable about the ENVISAT ground segment. The basic
calculator allows the user to convert between various time formats
officially used in the ENVISAT ground segment e.g. in product or auxiliary
files. The advanced calculator allows the same conversion with an
additions conversion to/from on-board time. |
