Blizzard of 2016
True Colors VIIRS Imagery shows the snowy aftermath of the Blizzard of 2016 (click to enlarge)
In mid-January, both European and US numerical weather
predication models began to show the possibility of a severe
winter storm that would impact the US East Coast. These
predictions came to fruition as the storm dumped 18+ inches of
snow over an area stretching from Kentucky to New York City on
January 23-24. Areas in West Virginia and western Maryland
received as much as 40 inches of snow,while most of major
northeastern cities approached or broke their previous snowfall
records.
STAR JPSS scientists have provided high resolution images and
product maps covering the impacts of this blizzard for the
Northeastern US. A webpage including the latest imagery can be
found at https://www.star.nesdis.noaa.gov/jpss/Blizzard2016.php.
This webpage allows for viewing and comparing the surface
conditions before and after Blizzard 2016. VIIRS visible imagery
and many JPSS products including the snow impacts on coastasl
turbidity are collected on the website.

After about two and a half years development, the GOES
Evapotranspiration and Drought Product (GET-D) System has passed
the Operational Readiness Review on February 5, 2016 and is
approved to go to operation by the SPSRB on February 17. The
GET-D system uses observations of solar insolation and land
surface temperature from NOAA GOES-East and GOES-West Imagers to
derive daily evapotranspiration over North America during clear
conditions. The daily evapotranspiration (ET) is needed for
validation of the ET simulations of the numerical weather
prediction models used by NCEP. The daily ET is further used to
derive an Evaporative Stress Index (ESI) which is an indication
of soil moisture status. Negative anomalies of ESI compared to
climatology are in turn indications agricultural drought. The
ESI drought monitoring products have been used to NCEP CPC
monthly drought briefing and the National Integrated Drought
Information System (NIDIS) that is currently the most used
drought information sources for the United State and the world.
The operational GET-D will provide NIDIS seamlessly with drought
information independent from almost all other drought
information sources. The GET-D system is developed by STAR
scientists and will be operational at OSPO.

K. Pryor has generated and delivered GOES Fog Detection
product imagery and datasets for an ice fog event over the Salt
Lake City metropolitan area that occurred on January 9, 2015 in
support of the Mountain Terrain Atmospheric Modeling and
Observations (MATERHORN) program. MATERHORN is a joint effort
between the Naval Postgraduate School, University of Notre Dame,
University of California, University of Utah, and University of
Virginia designed to investigate complex-terrain meteorology
over diverse scales, topography, and forcing mechanisms. During
this fog event, the GOES Fog product, derived from the
brightness temperature difference between GOES-15 band 2 (SWIR)
and band 4 (LWIR), effectively distinguished regions of fog from
regions of clear skies in the Salt Lake City area. Figure 2
shows fog detected by GOES near Salt Lake City International
("SLC") and Brigham City ("BMC") airports where visibilities were
observed to be less than two miles in fog at 1300 UTC. Near that
time at Ogden airport ("OGD"), no fog was indicated by GOES,
with a surface weather observation of clear skies and
unrestricted visibility.

Yong Han was invited to attend the Meteosat Third Generation
(MTG) Infrared Sounder (IRS) mission advisory group topical
meeting on Level 1 processing. He gave the presentation with the
title "CrIS Spectral and Radiometric Calibration". In this two-
day meeting, 20 presentations were presented by people mainly
from the EUMETSAT community, and discussions were focused on
issues related to instrument design, L1 processing algorithms,
data format and user requirements.
The main outcome is the document that summarizes the
recommendations and action items for the generation of level 1
IRS data with the level of quality required by the user
community. IRS is an imaging Fourier Transform spectrometer
based on a Michelson interferometer, two detector arrays
(160x160), a scan mirror. Each detector arrays covers 640x640
km2 with a single pixel size of 4 km2. The
instrument measures radiation in the two spectral bands: LWIR
(700-1210 cm-1) and MWIR (1600-2175 cm-1),
with a uniform spectral resolution 0.625 cm-1. The
first IRS onboard MTG will be launched into orbit in 2022.

February 25 - The PSR for the ABI FM3 was
conducted at the Harris/Exelis facility in Ft. Wayne, IN. ABI is
a key payload for the GOES R-Series. X. Wu and B. Efremova,
members of the GOES-R Calibration Working Group, attended the
review and briefed the GOES-R Program Scientist prior to the
review on CWG assessment of ABI FM3 science performance. An
unprecedented section of this PSR was lessons learned from
Advanced Himawari Imager (AHI), a similar instrument launched in
October 2014 and currently operated by Japan Meteorological
Agency (JMA). CWG members were instrumental in promoting the
NOAA-JMA cooperation on advanced geostationary meteorological
satellite programs that enabled these lessons learned.
In particular, CWG led the discovery and characterization of
3.9 µm channel stray light that helped the identification of the
root cause and the timely correction for all ABI FMs. Overall the
Integrated Independent Review Team found that the instrument is
stable; verifications have nearly completed; lessons learned have
been properly applied; and the TVAC analyses were thorough.

February 22-26 - A.Reale was extended an
invitation by Dr. Thomas August, Hyper spectral Sounders Level 2
Team Leader, Remote Sensing and Sounding Division, to visit
EUMETSAT (Darmstadt, Germany) and provide training seminars on
conducting atmospheric profile validation using the NOAA
Products Validation System (NPROVS) developed and operated at
STAR. Training was also extended to staff participating in an
ongoing European Union Copernicus/Horizon-2020 Research and
Innovative Programme proposal entitled "Gap Analysis for
Integrated Atmospheric Environmental Climate Variable (ECV)
Climate Monitoring (GAIA-CLIM)" to which NOAA contributes as a
3rd party with a focus on satellite collocations with reference
observations from GCOS Reference Upper Air Network (GRUAN).
The training consisted of 2-days of training focused on
NPROVS+ applications relevant to GAIA-CLIM followed by 3-days of
training focused on applications relevant to EUMETSAT hyper
spectral sounder L2 products group. A photo of the core
participants in the training is shown in the panel below. A.
Reale also provided a general seminar to EUMETSAT staff on
Friday, 26 February. High interest was evident to leverage
NPROVS at EUMETSAT in ongoing projects focused on the analysis
of atmospheric temperature and moisture sounding (geophysical
and radiometric) from satellites and the ground, including
recommendation to consider establishing an NPROVS User Group
(NUG). Consideration for follow-up training in conjunction with
the planned EUMETSAT Satellite Conference and GCOS G-VAP Working
Group activities in Darmstadt later this year is pending.

March 5, 2016 - Over 60 calibration scientists and researchers representing
almost all of the major meteorological and space agencies
operating Earth remote sensing satellite instruments attended
the GSICS Research Working Group and Data Working Group (GRWG
and GDWG) 2016 Annual Meeting at JAXA in Tsukuba and exchanged
information on new results, methods, and instruments. The first
day was taken up by a mini-workshop with emphases on the moon as
a calibration target and on calibration comparison results for
recently launched JAXA and JMA instruments. Major
accomplishments reported and discussed in the rest of the
meeting include the first operational products from EUMETSAT
and progress on new demonstration products from the Chinese
Meteorological Agency (CMA), the Korean Meteorological Agency
(KMA), and the Indian Meteorological Department (IMD).
Calibration comparisons using the Deep Convective Cloud (DCC)
method dominated the special session on visible sensors. NOAA
products will begin demonstrating this new approach. L. Flynn,
the GSICS Coordination Center Director and UV Subgroup Vice-
chair, provided four talks on the GCC Annual Report, defining
GSCIS products, the GSICS Users' Workshop and solar ultraviolet
References.

March 8-10, 2016 - B. Kuligowski attended
5th meeting of the CEOS Working Group on Disasters,
hosted by Deutsches Zentrum für Luft- und Raumfahrt (DLR) in
Bonn, Germany. As the co-chair of the Thematic Pilot for Floods,
he presented an update on Flood Pilot activities during the past
6 months and participated in discussions on how the activities
of the Pilot might be maintained after the Pilot period ends in
December 2017.
Importance: The purpose of this working group is to enhance the
use of earth observation (EO) data in disaster risk management by
strengthening the linkages among satellite data providers, the
creators of value-added products, and the potential users of those
products. Three pilot projects focusing on floods, seismic
hazards, and volcanoes are coordinating and leveraging ongoing
efforts to provide relevant EO data to users and to develop and
strengthen their capacity to use these data in decision-making; an
additional Pilot for landslides was recently initiated. In
addition, a recovery observatory has been created to improve the
use of EO data in longer-term recovery after a disaster occurs.
The intent is for these Pilots to lead to a sustained effort to
make better use of EO data in managing, responding to, and
recovering from flood disasters.
