Method Detail

TG_FTOI

public static int[] TG_FTOI(int[] iftime,
                            int start)

This subroutine converts the two integers stored in a grid file into three integers containing the date, time and forecast time.

Parameters:

iftime - input time array

start - offset into the array

Returns:

int[3] with date time and forecast time

TG_ITOC

public static String TG_ITOC(int[] intdtf)

This subroutine converts an integer time array containing the date, time and forecast time into a GEMPAK grid time.

Parameters:

intdtf - integer array of date, time and forecast time

Returns:

formatted string

TG_CFTM

public static String[] TG_CFTM(int ifcast)

This subroutine converts an integer grid forecast time into the character forecast type and time. The forecast type is A (analysis), F (forecast), G (guess) or I (initialize). If the forecast time is less than 100 and the minutes are 00, only hh is returned.

Parameters:

ifcast - integer forecast time

Returns:

type and time.

TI_CDTM

public static String TI_CDTM(int idate,
                             int itime)

This subroutine converts an integer date (YYMMDD) and time (HHMM)

Parameters:

idate - integer date

itime - integer time

Returns:

string date/time

TI_ITOC

public static String TI_ITOC(int[] idtarr)

This subroutine converts an integer time array into a standard GEMPAK time. The integers are checked for validity.

Parameters:

idtarr - Time array (YYYY,MM,DD,HH,MM)

Returns:

time as a string

TI_DAYM

public static int TI_DAYM(int iyear,
                          int imon)

This subroutine returns the number of days in the given month. The year must be a full four-digit year.

Parameters:

iyear - integer year

imon - integer month

Returns:

number of days

LEAP

public static boolean LEAP(int iyr)

Check for leap year

Parameters:

iyr - year to check

Returns:

true if leap year

ST_INCH

public static String ST_INCH(int value)

Convert a value to a string

Parameters:

value - value to convert

Returns:

string representation

ST_ITOC

public static String ST_ITOC(int value)

Convert the int bits to a string

Parameters:

value - value to convert

Returns:

string representation

ST_ITOC

public static String ST_ITOC(int[] values)

Convert the int bits to a string

Parameters:

values - array of values to convert

Returns:

string representation

ERMISS

public static boolean ERMISS(float value)

Test for missing value

Parameters:

value - value to check

Returns:

true if missing

LV_CCRD

public static String LV_CCRD(int ivcord)

This subroutine translates a numeric value for IVCORD into its character value in VCOORD.

Parameters:

ivcord - integer coordinate value

Returns:

string coordinate name

swp4

public static int swp4(int value)

Swap the order of the integer.

Parameters:

value - array of int values

Returns:

swapped value

swp4

public static int[] swp4(int[] values,
                         int startIndex,
                         int number)

Swap the order of the integers in place.

Parameters:

values - array of int values

startIndex - starting index of the array

number - of bytes

Returns:
