Description

Significance

Animation Zoom improvements

Animations can be halted and zoomed without the zoom being applied to all animation images. The user may elect to resume animation with or without the zoom.

Animation High Resolution Retrieve

Animation controls allow users to pull up a higher resolution image of an interesting feature while the animation is halted. The higher resolution image can be dismissed, or can be used to start a new animation (see figure 5).

Sun Corrected POES. Sun angle correction was previously available only on GEO visible

channels and MSIs

.

This correction is now available on NOAA imagery, improving NOAA GEO visible channels and MSIs in low-light orbits and high latitudes.

Client Applications compatible with

Windows Vista

Previous clients ran only on Windows XP standard desktop configuration, and Windows 2000 O/S.

Day Night Visual Indicator

Shows a day/night terminator on infrared imagery, indicating when/where visible imagery is available (see figure 4).

Image Navigation provides feedback

Now when users shift the maps, the GUI displays the East-West, North-South and total shift distance.

The animation high-resolution retrieve function allows users to analyze features of interest in an animation with a higher resolution image, and provides the option to dismiss the new image or start a new animation with it. This is done after halting the animation, selecting the expansion-box icon (arrow #1), selecting the resolution size on the retrieval GUI (arrow #2), positioning the wirebox (arrow #3), and selecting “OK” on the retrieval GUI (arrow #2).

Example: Improved High-Res Retrieve

Slide10

The new servers provide two projected Areas of Interest. AOI #1 is always centered on the local direct readout system for DMSP and NOAA polar satellite collection. The examples above show that the Sembach system has set the ingest system for North Polar Stereographic, which sets the Data Server AOI #1 to the same projection.Also note the temperature scale has been added to the infrared color annotation bar at the bottom of the images. 

Example: Sembach AOI

#1

Slide11

The second AOI on the new servers can be set to Stereographic, Geographic or Mercator, and centered on a different location. The Sembach examples above show (left) Data Server #2, AOI #2 is set to 20N 00E or Met-9, and (right) Data Server #1, AOI #2 is set to 20N 40E for Met-7.Also note that the product/time text in the upper left now has a contrasting background. The previous clients overlaid only text onto the imagery without a text background, and the image colors sometimes made the text hard to read.

 

Example: Sembach DS2 and DS1 AOI

#2

Slide12

The Data Servers can create projected MSIs. On the left is a Met-7 Day Fog-Stratus MSI from Sembach DS2, AOI #2. On the right is a Day Fog-Stratus MSI manually created from FY-2D projected channels retrieved from the Kadena system. The manually created projected MSI does not have sun angle correction (not available with projected visible images on the client), while the server-built projected MSI does. 

Example: Projected MSIs

Slide13

The Day/Night indicator line (with Sun and Moon symbols) can be used with all Mark IVB imagery types, but was originally requested for use with Infrared images and animations. Since all times are in Zulu, and infrared imagery users may be half a world away from the imagery area, this tool can be used to indicate when and where GEO or polar visible images and visible-based MSIs are available, rather than pulling a few (or many) preview images. Also note the enhancement color bar (left image, on the bottom) now offers a temperature scale for thermal infrared, water vapor and microwave imagery.

Example: Day/Night Indicator Overlay

Slide14

Next Mark IVB Upgrades

Contract Modified to Add MetOp

Currently adding stored ‘complete orbit’ data at Sembach system

Described in the following slides

Direct Readout capability to be added soon

AHRPT broadcast requires a firmware upgrade

Firmware upgrade will facilitate FY-3 series collection

On contract to upgrade for X-Band modification

Third antenna being added to current sites

Required for Aqua

and Terra collection

Will support NPP and NPOESS collection

Will also collect NOAA and DMSP

Will reduce single tracking antenna schedule conflicts

Developing a two tracking antenna system for new sites

Slide15

Europe’s MetOp Series Lifespan: 2006-2020

MetOp

Stored AVHRR is high resolution

NOAA Stored AVHRR (GAC – Global Area Coverage) is lower resolution

Slide16

Getting Recorded MetOp AVHRR to Users via EUMETCast

MetOp-A recorded global data is dumped to the CDAS site at Svalbard, Norway

Relayed to EUMETSAT Headquarters, in Darmstadt, Germany

EPS Global Data Service is uplinked to EUMETCast for Europe, via Ku-band

MetOp stored data is received at the 21 OWS MARK IVB via the EUMETCast receiver

To Suitland

Slide17

Separate recorded MetOp, DMSP & NOAA data into several North-aligned Segments

A 101 minute orbit is too long to fit into the Mark IVB preview windows or image area, and must be broken into segments

Ascending sections of the orbit (travelling South to North) would be oriented “upside-down” (South-is-up).

The orbits are broken into

North-aligned

segments.

A Few Multispectral Examples

Slide24

Stratus in the Tropics and Sheared Tropical Cyclones at NightThere are some problems with infrared imagery. Longwave infrared imagery may not clearly show

low clouds

near

weak or sheared

tropical cyclones, and color enhancements that target stratus may not highlight these clouds clearly.

Low clouds may have temperatures similar to the sea surface and provide a poor contrast. Low clouds may also have a poor contrast with nearby thin cirrus, which can be contaminated/mixed with warmer emissions from the sea surface below. Also, tropical water vapor partially attenuates the emissions of

stratiform

clouds.

The

longwave-midwave

infrared channel difference is used to create a

night fog stratus

(

MFS

) product, which is colorized with an enhancement table, but the enhancement is

designed for highlighting fog and stratus in mid-latitude

continental regimes with smaller cloud droplets and less water vapor.

The Naval Research Labs has a modified channel difference product that accounts for the differences due to the larger maritime cloud droplets and higher water vapor values. The channel difference is the same as the

MFS

, but the range from -3 to +3 is stretched to highlight the ocean surface features and stratus better.

Standard server multispectral images (

MSIs

), such as the

IR

Fog (

FIF

) may highlight nighttime features to help monitor storm environment and changes. Other recently developed

MSIs

are not

yet added

to the server, but

may be built on the client with recorded functions

.

False color MSIs are red-green-blue composites constructed from two or more different parts of the visible-infrared spectrum. The most common false color is a two-channel false color that uses visible imagery in the red and green video inputs, and an LWIR image in the blue input.

The atmosphere absorbs energy at some wavelengths (absorption-emission bands) and allows energy at other wavelengths to travel downward and upward with minimal absorption (atmospheric windows).

These are the parts of the spectrum measured by METSAT imagers, and their MARK IVB channel names.

With experience, one can tell with the BD enhancement that there are areas of stratus North of Typhoon Fitow. The ocean to the West has some cumulus, but is clear.

Longwave IR and Water Vapor

Slide27

The LWIR - MWIR JTWC Tropical false color (FJT) on the left, and the LWIR - Water Vapor (FJW) at right show high and mid level clouds, while the FJW also shows areas of abundant upper level water vapor. One can see hints of low clouds to the North in the FJT image.

Slide29

The updated IR Fog (FIF) is shown on the left with the updated IR FogN (FF3) at right.

The two areas of stratus North of Typhoon Fitow are highlighted, and mid and high level clouds are presented clearly better than the MFS and TLE products, but the cloud-free ocean features to Fitow’s West are more subdued.

Updated IR Fog MSIs

FIF and FF3

Slide30

Using Recorded Functions for the New FIF, FF3 and TLE MSIsMark IVB multispectral products are usually built on the server when users request the products. The Mark IVB 11.10.0205 and 11.10.0303 upgrades include the modification to the FIF (IR Fog) MSI.

The other MSIs are not included in this upgrade cycle, but users can also build MSIs on the Mark IVB client application.

Mark IVB client users can obtain recorded functions and save them to the function directory. Once the functions have been saved there, they are available for use with downloaded imagery.

The new functions are:

Convert_MFS-to-TLE.ftn

GeoWV-IR_NightMSI.ftn

NewIR-Fog_FIF-FF3-TLE.ftn

The default location for the functions directory is: C:\documents and settings\m4b_data\dat\commands\

NOTE: Mark IVB client users can define their preferred data directories to different folders, or a different local drive or a shared network drive.

Slide31

The “Convert_MFS-to-TLE” function requires the MFS (Night Fog Stratus) product in work area 1.

The “

GeoWV-IR_NightMSI

” function requires the user load Water Vapor and Thermal Blue images into work areas 1 and 2, respectively.

3. For the “FIF, FF3, and TLE” function, imagery must be loaded in work areas 1, 2, 3 and 4 in this order:

GOES, FY-2, and/or MTSAT

After the images are loaded, then the user selects the NewIR-Fog_FIF-FF3-TLE function.

NOTE #1: Meteosat-7 does not have the low cloud (MWIR) or split window (Thermal Blue and Red) channels necessary for the FIF, FF3, FJT, MFS or TLE MSIs.

NOTE #2: Meteosat-7 and all other GEOs can be used to build the FJW MSI, day or night.

NOTE #3: Once any function is used, you can get to it faster by right-clicking on the Function icon for a pop-up list of the most recently used functions for a frequent use.
