gov.noaa.ncdc:C00004 National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce Unknown tabular digital data http://www.ncdc.noaa.gov The National Climatic Data Center (NCDC) has, in archive, the digital data set Gridded Atmospheric and Ocean Data (DSI-9934), which was provided by the U.S. Navy Fleet Numerical Meteorology and Oceanography Center and its predecessors. The geographic coverage is the global ocean. The time period covered is November 1961 through December 1995. The specific parameters in this data set makes a list that is too long to present in a brief abstract. The parameter keywords section gives some idea of the scope of the parameters. Parameters are sufficient to describe, at each grid point, the upper air and surface meteorological conditions as well as the ocean surface and oceanographic conditions. To make a wide range of climatic data available to researchers and the public. data set C00004 ANEMOMETERS BAROMETERS DEWPOINT SENSORS DRIFTING BUOYS EPSONDE HUMIDITY SENSORS HYGROMETERS PRESSURE GAUGES PRESSURE SENSORS PYRANOMETERS RADIOMETERS RADIOSONDES RAWINSONDES TEMPERATURE PROBES TEMPERATURE SENSORS THERMOMETERS VISUAL OBSERVATIONS WAVE HEIGHT GAUGES WIND VANES BALLOONS BUOYS RADIOSONDES SHIPS National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce 19611101 19951231 Ground Condition Complete As Needed -180.0 180.0 90.0 -90.0 ISO 19115 Topic Category climatologyMeteorologyAtmosphere 004 elevation 006 environment 007 oceans 014 DIF Discipline Keyword Thesaurus Earth Sciences > Atmosphere > Meteorology Earth Sciences > Atmosphere > Climatology Earth Sciences > Atmosphere > Weather Earth Sciences > Ocean > Oceanography GCMD Sciences Keyword Valids EARTH SCIENCE > ATMOSPHERE > ALTITUDE > GEOPOTENTIAL HEIGHT EARTH SCIENCE > ATMOSPHERE > ALTITUDE > PLANETARY BOUNDARY LAYER HEIGHT EARTH SCIENCE > ATMOSPHERE > ALTITUDE > TROPOPAUSE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > FOG EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > ANTICYCLONES/CYCLONES EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > ATMOSPHERIC PRESSURE MEASUREMENTS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > PRESSURE ANOMALIES EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > PRESSURE TENDENCY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > PRESSURE THICKNESS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SEA LEVEL PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SURFACE PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > HEAT FLUX EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > SOLAR RADIATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > TEMPERATURE PROFILES EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > TEMPERATURE TENDENCY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > VIRTUAL TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > DEW POINT EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > EVAPORATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > UPPER LEVEL WINDS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > VERTICAL WIND MOTION EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD AMOUNT/FREQUENCY EARTH SCIENCE > ATMOSPHERE > CLOUDS EARTH SCIENCE > ATMOSPHERE > PRECIPITATION EARTH SCIENCE > OCEANS > BATHYMETRY/SEAFLOOR TOPOGRAPHY EARTH SCIENCE > OCEANS > OCEAN CIRCULATION > OCEAN CURRENTS EARTH SCIENCE > OCEANS > OCEAN CIRCULATION > OCEAN MIXED LAYER EARTH SCIENCE > OCEANS > OCEAN CIRCULATION > WIND-DRIVEN CIRCULATION EARTH SCIENCE > OCEANS > OCEAN HEAT BUDGET EARTH SCIENCE > OCEANS > OCEAN TEMPERATURE > SEA SURFACE TEMPERATURE EARTH SCIENCE > OCEANS > OCEAN TEMPERATURE > THERMOCLINE EARTH SCIENCE > OCEANS > OCEAN TEMPERATURE > WATER TEMPERATURE EARTH SCIENCE > OCEANS > OCEAN WAVES > SIGNIFICANT WAVE HEIGHT EARTH SCIENCE > OCEANS > OCEAN WAVES > SWELLS EARTH SCIENCE > OCEANS > OCEAN WAVES > WAVE HEIGHT EARTH SCIENCE > OCEANS > OCEAN WAVES > WAVE PERIOD EARTH SCIENCE > OCEANS > OCEAN WAVES > WAVE SPEED/DIRECTION EARTH SCIENCE > OCEANS > OCEAN WAVES > WIND WAVES EARTH SCIENCE > OCEANS > OCEAN WINDS > SURFACE WINDS GCMD Location Valids GLOBAL OCEAN GCMD Location Valids SEA SURFACE STRATOSPHERE TROPOSPHERE SHIPS ANEMOMETERS SHIPS BAROMETERS SHIPS DEWPOINT SENSORS SHIPS EPSONDE SHIPS HYGROMETERS BUOYS DRIFTING BUOYS SHIPS PRESSURE GAUGES SHIPS PRESSURE SENSORS SHIPS PYRANOMETERS SHIPS RADIOMETERS SHIPS TEMPERATURE PROBES SHIPS TEMPERATURE SENSORS SHIPS THERMOMETERS SHIPS VISUAL OBSERVATIONS SHIPS WAVE HEIGHT GAUGES SHIPS WIND VANES BUOYS ANEMOMETERS BUOYS BAROMETERS BUOYS HUMIDITY SENSORS BUOYS HYGROMETERS BUOYS PRESSURE SENSORS BUOYS TEMPERATURE PROBES BUOYS TEMPERATURE SENSORS BUOYS THERMOMETERS BUOYS WAVE HEIGHT GAUGES BUOYS WIND VANES RADIOSONDES RADIOSONDES BALLOONS RAWINSONDES 1 None None Not provided Unknown Completeness information not available.

This number is the sum of total field (section) bytes (data point, identification, etc.). 16 Bits D - depth of compaction it a compaction field 2 Bits C - classification of product 0 = unclassified 1 = classified 1 Bit Number of 24 bit words in Identification Field, inclusive from word 0 to the first word of data. 5 Bits Units Code for units of data 0 = degrees F 1 = degrees A 2 = degrees C 3 = meters 4 = meters/sec (m/s) 5 = knots 6 = miles/hr 7 = mb 10 = cm 11 = (m/s)^2 12 = feet 13 = degrees/10 (compass direction) 14 = seconds 15 = g cal/cm^2/day 16 = nm/day 17 = cm/sec 20 = probability code 21 = C deg /10^4km^2 22 = degrees (compass direction) 23 = dimensionless 24 = percent 25-37 = reserved for additional units 5 Bits Scale Factor This value represents the number of fractional Bits (integer scaling) relative to a 24 bit word, for fixed Point data values contained within this field. Unit conversion Scaling is not included. This value is an integer with the range (77 to 00). 6 Bits Z - This bit indicated the datum in the field has been extracted (zoomed) from and is a subset of a larger field. If the field is reanalyzed, this will be noted in the field identification area. This bit also indicates the presence of the constants described in rows 26 through 29. If this bit is not set the above words have been deleted. 1 Bit K1 - This bit indicated the presence of the constants described in rows 18 through 25. This bit will be set for all fields for the first section. This bit will also be set for all sections of fields which have more than 32 sections. If this bit is not set, rows 26-29 have been deleted. 1 Bit K2 - This bit indicated the presence of the constants described in rows 30-33. If this bit is not set, the above words have been deleted. 1 Bit S - This value indicates if this field is the first of a number of sections. S = 1 - first or only section S = 0 - succeeding section 1 Bit Section Number This value represents the section number of the total data field. This number descends with succeeding sections, i.e., the first section contains highest section number which serves as a count of the total number of sections. For fields having greater than 32 sections, SS (item 22) will be used as the most significant bits as an extension of this number and K1 (Item 12) will always be set. 5 Bits FTC - This binary number represents the number of 24 bit words contained in the Field Title. A value of zero is not permitted. The range of values are 0 Less than FTC Less than or equal to 15. 4 Bit Checksum This word is the ones compliment of the algebraic sum of the data field/section. This includes the identification portion and data, but not the checksum word. 24 Bits The following constants will be present only if the bit described in row 12 is set to a "1". M - This value represents the number of grid columns in the data field. 12 Bits N - This value represents the number of rows in the data field. 12 Bits Re/d or Rm/d a. Re/d - Polar Stereographic Projections - For polar stereographic grids, this entry is Re/d, the distance from the pole to the equator on the projection divided by the mean mesh distance of the given grid field (e.g. on the FNWC 63x63 polar stereographic grids, this value is Re/d = 11,889.1 Km/381 Km = 31.205). b. Rm/d - Mercator and Spherical Grids - For the Mercator (global band) and spherical grids, this entry is Rm/d, the mean radius of the earth divided by the mean mesh distance on the given grid field (e.g., on the FNWC 73x144 spherical grid this value is Rm/d = 6371.229 Km/278.) Km = 22.918.) c. The value of Re/d or Rm/d has a binary scale factor of S6. 16 Bits Data Format Used to indicate one of several data formats and the number of bits per data point, in binary. 0 = scaled data 24 bits 1 = scaled data 16 bits 2 = scaled data 20 bits 3 = band index 12 bits 4 = band index 24 bits 5 = compact spiral 6 = compact rows 7 = compact pen commands 10 = calcomp pen commands 11 = compact vectors 12 = compact columns 13-17 = not used 4 Bits SS If the section number (item 15) of a field exceeDSI-3210 these bits will serve as an extension for the most significant portion. 2 Bits Long.X a. Polar Stereographic Grids For polar stereographic grids, Long.X is defined as the longitude line which is parallel to the J-axis of the grid, such that a vector along that longitude from the pole to the equator (in the hemispheric grid from which the subject grid has been extracted in the case of a zoom) is (1) in the opposite direction from the J-axis in the Northern Hemisphere and (2) in the same direction as the J-axis in the Southern Hemisphere. The longitude in defined on a compass which sweeps from 0 degrees to 360 degrees, east to west. This integer has an integer binary scale of factor S3. b. Mercator and Spherical Grids This parameter should be set to zero for standard Mercator and Spherical grids. (Non-zero values may be specified at a later date if it becomes necessary to allow for rotation of these grids.) 12 Bits PR - This value indicated the type of projection for the data field. The values assigned so far are: PR = 0 - polar stereographic (true 60 degrees N) = 1 - mercator (global band) = 2 - spherical coordinates 3 Bits Delta i Pole or Delta i Ref This value represents the number of grid intervals on the M(i) direction to the reference point for the grid, relative to the origin. (In the case of polar stereographic grids, the reference point in the North or South pole.) This value has an integer binary scale factor of S5. This value represents the number of grid intervals in the N(j) direction to the reference point for the grid, relative to the origin. This value has an integer binary scale factor of S5. 15 Bits Extracted or Zoom Arguments These words, only present if the bit described in row 11 is set to "1", describes those arguments used to extract or zoom this field from a larger field.
