Times when the aircraft was in the no data cone for the NEXRAD
Sharon Lewis
Analysis last updated May 6, 2003


CAPPI plots where the a/c is flying inside the cone

000604:
take off - 2022
2022 - 2038 on the edge of the gridding
2053 probably passes over, but not enough reflectivity to define the hole
2302 probably passes over, but not enough reflectivity to define the hole
probably landing, but not enough reflectivity to define the hole

000607:
No NEXRAD

000611:
1820 - 1831
1831 - 1845
1857 - 1905
1913-1916
1931 - landing either in the cone or within 10 km

000612:
1421-1435
1748 - land

000613:
takeoff - 2046
2102-2105
2120-2124
2135-2138
2206-2211
2416-land

000614:
No NEXRAD

000617:
take off - 1609
1630 - 1643

000620:
I presume during take off and landing, but there was not a significant source of reflectivity over the radar to define the hole in the CAPPIs
2236-2239 close to edge of gridding
2248 - 2327 a/c is on (or off the edge) of the gridding

NO reflectivity in the NEXRAD MER plots for this day

000623 - flt1:
1654-1707 equals one volume (DATA GAP)
1815 - 1906 either inside the cone or on the edge

000624 - flt1:
No NEXRAD

000624 - flt2:
No NEXRAD

000625:
No NEXRAD

000628 - flt1:
I presume during take off and landing, but there was not a significant source of reflectivity over the radar to define the hole in the CAPPIs

000628 - flt2:
take off - 1916
1927 - 1934
1940 - 2006
2113 - landing

There are no MER plots between 1850 and 1910 due to the gap in the radar files at 1919-1924, but the a/c position still looks to be on the edge of (or inside) the hole the a/c continues in the region of the cone until 2006

010522:
take off to 2136
2221 - 2230
2427 - landing

010525:
take off to 1900 a/c track looks bad
2146 - landing (either in cone, or on the edge)

010527:
Not very much reflectivity in the region of the NEXRAD cone, and the a/c wasn't close enough to worry about

010528:
none, take off and landing are not well represented in the CAPPIs

010529:
take off to 1949
2105-2112 edge of gridding
2240 to landing

010602:
take off to 1854
2154-2158 edge of gridding
2252 to landing

010604:
This is the day the radar data range was extended beyond 150 km
take off - 1930
There is a gap between beams that is evident in the 4km cappi during
2031-2230
Times that MIGHT be OK are: 2115-2124
2133-2146
2201-2213
2230-2241
2101 - 2103 a/c is at the edge of the gridding
2152-2154 on edge
2218-2222 on edge
2258 to landing

010605:
I presume during take off and landing, but there was not a significant source of reflectivity over the radar to define the hole in the CAPPIs

010606:
I presume during take off and landing, but there was not a significant source of reflectivity over the radar to define the hole in the CAPPIs
1928-1930 a/c is at the edge of the gridding
1938-1941 a/c is at the edge of the gridding
1952-1954 a/c is at the edge of the gridding
2015 - land

010607:
takeoff - 1732
1742-1745 a/c is on the edge of the hole
1921-1925
2010-land

010610:
takeoff - 2018
2246-2249 a/c is at the edge of the gridding
2259-2306 a/c is at the edge of the gridding
current NEXRAD CAPPIs stops at 2311

010615:
takeoff-2126
2252-2342 either in the cone or on the very edge of it
2355 - landing either in the cone or on the very edge of it

010618:
take off to 2032
2055 - 2059 a/c turns around in the cone
2112 - 2118 a/c turns around in the cone
2132-2139
2155-2202
2207 - landing

No MER plots for NEXRAD for this day

010623:
take off - 1833
1946 - 1951 on the edge of the cone
2002 - landing

MER plots stop at 1950

010624:
