In this study, daily maps of snow cover distribution and sea ice extent produced by NOAA’s interactive multisensor mapping system (IMS) were validated using in situ depth data from observing stations obtained National Climatic Data Center (NCDC) for calendar years 2006 to 2010. IMS provides within the Northern Hemisphere combination geostationary polar orbiting satellites visible, infrared microwave spectrums. Statistical correspondence between point measurements has been evaluated assuming...
Abstract In 2011, the National Oceanic and Atmospheric Administration (NOAA) began a cooperative initiative with academic community to help address vexing issue that has long been known as disconnection between operational research realms for weather forecasting data assimilation. The is gap, more exotically referred “valley of death,” efforts within broader NOAA’s activities, which are heavily driven by constraints. With stated goals leveraging benefit mission offering path operations...
The purpose of this paper is to investigate whether a logical chain events can be established explain the abrupt climatic regime shift changes in Pacific that link atmosphere ocean fisheries impacts. investigation endeavors identify synchronous series data sets establish feasibility climate change often referred as shifts. study begins by using biological (fish catch/stock) markers mathematically dates change. are confirmed literature search parameters also show on same dates. Using date...
Based on the ensemble spread, a methodology of measuring uncertainty in weather forecasts, temperature trend and spread have been estimated using five radiosonde data sets seven reanalysis products beginning 1989. The results show that magnitude warming or cooling depends sources, atmospheric heights, geophysical latitudes. Over low‐middle latitudes, varies from −2.6 K/decade NCEP‐DOE to −0.8 HADAT2 lower stratosphere. weakly changes 0.2 through 0.4 middle troposphere. Antarctica, there is...
An investigation was conducted to assess whether a chain of events could be established explain the global 1977–78 climatic regime shift and its potential association with ecosystem change. Changes in eastern Pacific will investigated goal demonstrating that there is link between changes stratosphere ocean consequent impacts on fisheries. This focuses forcing mechanisms, including coupled solar atmospheric dynamic appear associated how they may have resulted surface circulation subsequent...
Abstract. The CREST-Snow Analysis and Field Experiment (CREST-SAFE) was carried out during January–March 2011 at the research site of National Weather Service office, Caribou, ME, USA. In this experiment dual-polarized microwave (37 89 GHz) observations were accompanied by detailed synchronous meteorology snowpack physical properties. objective long-term field to improve understanding effect changing snow characteristics (grain size, density, temperature) under various meteorological...
The tropospheric and stratospheric temperature trends uncertainties in the fifth Coupled Model Intercomparison Project (CMIP5) model simulations period of 1979–2005 have been compared with satellite observations. data include those from Stratospheric Sounding Units (SSU), Microwave (MSU), Advanced Unit-A (AMSU). results show that CMIP5 reproduced common cooling (−0.46–−0.95 K/decade) warming (0.05–0.19 features although a significant discrepancy was found among individual models being...
Abstract. Using NOAA's Gridpoint Statistical Interpolation (GSI) data assimilation system and NCAR's Advanced Research WRF (Weather Forecasting) (ARW-WRF) regional model, six experiments are designed by (1) a control experiment (CTRL) five (DA) with different sets, including (2) conventional only (CON); (3) microwave (AMSU-A + MHS) (MW); (4) infrared (IASI) (IR); (5) combination of (MWIR); (6) conventional, observation (ALL).

Abstract. Using the fifth Coupled Model Intercomparison Project (CMIP5) model simulations and two observational datasets, surface temperature trends their discrepancies have been examined. The temporal-spatial characteristics for are discussed. Different from a constant estimated linear trend entire simulation period of 1850–2012, dynamical using running least squares fitting with moving 10 yr time windows calculated. results show that CMIP5 generally in good agreement measurements global...
Abstract On the basis of both composite and multiple linear regression analysis, three temperature datasets from two reanalyses one set satellite observations have been used to evaluate different responses in winter [December–February (DJF)] period as they relate solar forcing between pre‐ post periods data assimilation.

[1] The Suomi National Polar-Orbiting Partnership (SNPP) satellite was successfully launched into a 13:30 polar orbit on 28 October 2011. SNPP is the first in series of next-generation weather satellites Joint Polar Satellite System (JPSS). and JPSS provide continuation NOAA's Polar-orbiting Operational Environmental Satellites NASA Earth Observing Systems. carries following five instruments: Visible Infrared Imaging Radiometer Suite (VIIRS), Cross-track Sounder (CrIS), Advanced Technology...
Abstract. This investigation focuses on a global forcing mechanism for decadal regime shifts and their subsequent impacts. The proposed is that the atmospheric planetary waves can lead to changes in surface air–sea conditions subsequently fishery changes. In this study, five (1956–1957, 1964–1965, 1977–1978, 1988–1989, 1998–1999) most recent 59-year period (1950–2008) have been identified based Student t tests association with marine ecosystem change has discussed.
