Anvil Case 1 (Times: 2059 - 2302): This is an anvil study. The aircraft was frequently on the edge of the anvil, and other times close to the convection.
Case 2 (Times: 2312 - 2325): This was a brief (single pass) in a convective region.
000607 1755 - 1907 TBD Anvil Case 1 (Times: 1815 - 1852): A few brief moments through anvils. Mostly this is a convective flight.

Anvil Case 1 (Times: 1810 - 1826): This is anvil was just east of the 74C radar. There is no known lightning activity in the cloud in the observable past. Cell is in decay.
Case 2 (Times: 1828 - 1858): There was lightning activity in this cell about 1615. Last lightning was about 1705. Cell was in decay when the aircraft arrived. Aircraft flew on the edge of the anvil, not through the middle.
Case 3 (Times: 1901 - 1955): There was no known lightning in this cell in the observable past. The part of the anvil studied was fairly close to the generating convection.
000612 1415 - 1756 TBD NonAnvil Case 1 (Times: 1430 - 1730): Possibly a good case to study decay of electric fields and/or debris.
Case 2 (Times: 1730 - 1745): Aircraft was flying to the west of an active cell.
000613 2016 - 2424 TBD Anvil Case 1 (Times: 2045 - 2405): Good anvil study. Aircraft arrives in the early stages of anvil development and remains until little or no initiating convection is left. Lightning activity until 2145.
000614 2058 - 2424 Sharon Lewis
021003
Anvil Case 1 (Times: 2127 - 2158): This is a decaying anvil. The generating convection was gone before the aircraft arrived.
Case 2 (Times: 2212 - 2409): This case has multiple cells and multiple anvils. The anvil studied was a good case for studying the decay of an anvil.
000617 1551 - 1724 TBD NonAnvil Case 1 (Times: 1604 - 1724): This might be debris.
000620 2132 - 2349 TBD NonAnvil Case 1 (Times: 2150 - 2227): This was debris.
Case 2 (Times: 2228 - 2332): This is mostly convection.
000623 - 1 1636 - 1911 TBD NonAnvil Case 1 (Times: 1654 - 1718): The was out in front of an electrically active part of the storm.
Case 2 (Times: 1718 - 1744): This is debris. The core was electrically active at 1707.
Case 3 (Times: 1748 - 1752): This is debris, although there was never really a strong core here.
Case 4 (Times: 1756 - 1824): This is approximately the same position as Case 1. Given the eastward motion of the system, it is not the same cell.
000623 - 2 2050 - 2115 TBD NonAnvil Case 5 (Times: 2057 - 2110): This was a ferry flight. Most of the microphysics instruments were not turned on during this time.
000624 - 1 1624 - 1958 TBD NonAnvil Case 1 (Times: 1645 - 1945): This was an electrically active growing storm.
000624 - 2 2044 - 2343 TBD NonAnvil Case 2 (Times: 2100 - 2113): Aircraft passed through some debris.
Case 3 (Times: 2113 - 2225): Some 40dBZ areas appear at 4 km on the cappis along with some lightning activity.
Case 4 (Times: 2225 - 2332): The lightning was reducing in amount while the aircraft was there.
000625 1702 - 1817 TBD Anvil Case 1 (Times: 1710 - 1728): Just a simple, little cell without much lightning activity.
Case 2 (Times: 1728 - 1811): Anvil blowing off the the northeast.
000628 - 1 1400 - 1511 Sharon Lewis
020502
Anvil Case 1 (Times: 1404 - 1425): Last lightning occurred about 1305. It is possible the lightning that occurs at 1427, at (-40,-10) is this same cell.
Case 2 (Times: 1425 - 1456): Last lightning occurred about 1305.
000628 - 2 1809 - 2135 Sharon Lewis
020502
Anvil Case 3 (Times: 1815 - 1837): The "core" for this case is directly over the radar, inside the "radar void".
Case 4 (Times: 1837 - 2000): The aircraft missed most of the anvil for this case. It was usually sampled when the aircraft was turning around.
Case 5 (Times: 2003 - 2118): The aircraft remained too close to the core when sampling this anvil case.

Anvil Case 1 (Times: 1853 - 1913): The was a small anvil on the northern edge of the line.
Case 2 (Times: 1913 - 1931): If you go back to 1834 you will see that there was convection in the area, thus it was a debris cloud.
Case 3 (Times: 1931 - 1938): This part of the study was at the opposite end to the development of the convection.
Case 4 (Times: 1938 - 1944): This might be the same debris as case 2.
Case 5 (Times: 1944 - 2038): This is debris from the convective part of case 1. The aircraft might have been flying through some anvil after 2014.
Case 6 (Times: 2028 - 2200): Aircraft was flying close to convection.
010527 2125 - 2437 Monte Bateman
020221
Anvil Case 1 (Times: 2135 - 2201): Early stage of developing anvil.
Case 2 (Times: 2201 - 2222): This looks to have been part of the anvil studied in Case 1 that broke away, but the MER plots suggest it is debris. Did it dissipate, or was it consumed by a larger, growing anvil?
Case 3 (Times: 2222 - 2322): The anvil that collided with CAse 2. The flight covers more than one "finger" of the anvil.
Case 4 (Times: 2322 - 2409): This is a well developed 25-35 dBZ region at 4 km. It briefly develops a 35 dBZ region at about 2346.
Case 5 (Times: 2409 - 2422): This is the anvil associated with the decaying cell of Case 4.
010528 1802 - 2202 Monte Bateman
(date unknown)
Anvil Case 1 (Times: 1806 - 211120): Anvil attached to core initially producing lightning then decaying with time.
010529 1939 - 2248 Monte Bateman
020516
Anvil Case 1 (Times: 2006 - 2231): Small anvil attached to a long lasting active core. During the earlier part of the flight the aircraft was flying very close to the convection.
010602 1839 - 2258 Tony Grainger
020418
Anvil Case 1 (Times: 1914 - 2238): This is a rather large system. It might be more than one cell, but shortly after the aircraft arrived the was one dominant cell that as a large 45 dBZ region at 10 km.
010604 1840 - 2314 Jim Dye
020124
Anvil ase 1 (Times: 1901 - 1908): This shows precip going to the ground, but no cores.
Case 2 (Times: 1908 - 1921): This is very close to the radar data void and rather small so we can't really say much about it.
Case 3 (Times: 1921 - 1928): It is possible this anvil is from the cell studied in Case 1.
Case 4 (Times: 1928 - 2010): At this time this is a separate cell with some lightning. It will soon be taken over by the one to the south. This anvil becomes detached at about 2003.
Case 5 (Times: 2010 - 2259): This cell started off a moderate size when the aircraft took off, but it grew. The >= 45 dBZ region in the 4 km level at 2009 is abotu 40kmx30km with maximum > 60 dBZ.
010605 1759 - 2154 Eric Defer
020124
NonAnvil Case 1 (Times: 1820 - 1846 ): decayed convection. Last lightning about 1719 in this cell.
Case 2 (Times: 1853 - 1928 ) Althought the core is no longer at the position of the aircraft by looking at the animation it can be seen that the core was in this position.
Case 3 (Times: 1938 - 2044 ): A reverse search from the aircraft position shows that the core was there in the recent past.
Case 4 (Times: 2044 - 2116): Again, a core was at this location in the recent past.
010606 1733 - 2035 Natalie Murray
020307
NonAnvil Case 1 (Times: 1749 - 1815): a mass of several cells
Case 2 (Times: 1815 - 1921): debris
Case 3 (Times: 1921 - 2005): debris
Case 4 (Times: 2009 - 2020): moderate convection of multiple cells
010607 1717 - 2027 TBD NonAnvil Case 1 (Times: 1729 - 1936): t looks like this slows down as it approaches the coast.
Case 2 (Times: 1937 - 1950): anvil with no convecton
Case 3 (Times: 1950 - 2008): This used to be the convection that created the anvil in Case 2
Case 4 (Times: 2009 - 2017): Back through case 1?
010610 1958 - 2346 Tony Grainger
020110
Anvil Case 1 (Times: 2008 - 2042): A little bit of anvil at 2025, and some low level stuff at takeoff. Mostly this time fram is around convection with a lot of lightning.
Case 2 (Times: 2042 - 2133): Much of this is flown very close to the source.
Case 3 (Times: 2133 - 2210) : There was lightning associated with this part of the cloud about 2109 and bases are at leaste down to the 4km level. The last lightning in this part of the line was about 2130.
Case 4 (Times: 2210 - 2311): The aircraft does get close to the source about 2237 and 2240.
Case 5 (Times: 2311 - 2345) : Landing.
010615 2106 - 2406 Jim Dye
020321
Anvil Case 1 (Times: 2120 - 2146): complex cumulus
Case 2 (Times: 2146 - 2252): anvil in weakening line of convection
Case 3 (Times: 2252 - 2347): The reflectivity appears to stop at the radar. Perhaps due to some coastal effect?
010618 2007 - 2220 Paul Willis
020404
NonAnvil Case 1 (Times: 2032 - 2203): There was lightning in a cell to the west of the aircraft. There was 45-50 dBZ reflectivity with lightning in the region the aircraft flew at 1844. There is really no storm motion so this is debris.
* 010623 1816 - 2008 TBD NonAnvil Case 1 (Times: 1824 - 2006): This started off as a complex, cumulus of multiple cells with lightning. By the time the aircraft got there any reflectivity > 35dBZ was a good 75 km away and the radar screen is better described at "disturbed weather" (i.e. wide spread, sometimes pretty deep, "stuff")
010624 1757 - 2027 Frank Merceret
020919
Anvil Case 1 (Times: 1804 - 2024): The LDAR goes out about the time the aircraft arrives. The convective line is in an arc shape where the top of the arc and the bottom of the arc do not move in the same way.
010625 1920 - 2220 Eric Defer
020110
Anvil Case 1 (Times: 1952 - 204810): When the aircraft arrives at the anvil to cell 1 the cell itself is gone. The system is in decay and by 2140 the anvil is gone.
Case 2 (Times: 204820 - 2215): The aircraft flew way below the anvil associated with the 2nd cell which developed after the first.
010627 1434 - 1733 TBD Anvil Case 1 (Times: 1450 - 1457): The aircraft enters into the mass of cores.
Case 2 (Times: 1457 - 1615): The anvil is growing at this time and the maximums in the microphysics are probably due to close proximity to cores during turn arounds.
Case 3 (Times: 1615 - 1732): Again the aircraft turns around in cores. This is another part of the cloud system and probably has a different anvil source.
010628 1917 - 2127 Monte Bateman
020905
NonAnvil Case 1 (Times: 1925 - 2032): thick cloud, no convection
Case 2 (Times: 2032 - 2125): The aircraft is in another part of the cloud and way below it.
